  25 - An ACME protocol client written purely in Shell (Unix shell) language.
  26 - Full ACME protocol implementation.
  27 - Support ECDSA certs
  28 - Support SAN and wildcard certs
  29 - Simple, powerful and very easy to use. You only need 3 minutes to learn it.
  30 - Bash, dash and sh compatible.
  31 - Purely written in Shell with no dependencies on python.
  32 - Just one script to issue, renew and install your certificates automatically.
  33 - DOES NOT require `root/sudoer` access.
  34 - Docker ready
  35 - IPv6 ready
  36 - Cron job notifications for renewal or error etc.
  37
  38 It's probably the `easiest & smartest` shell script to automatically issue & renew the free certificates.

 120 # 1. How to install
 121
 122 ### 1. Install online
 123
 124 Check this project: https://github.com/acmesh-official/get.acme.sh
 125
 126 ```bash
 127 curl https://get.acme.sh | sh -s email=my@example.com
 128 ```
 129
 130 Or:
 131
 132 ```bash
 133 wget -O -  https://get.acme.sh | sh -s email=my@example.com
 134 ```
 135
 136
 137 ### 2. Or, Install from git
 138
 139 Clone this project and launch installation:
 140
 141 ```bash
 142 git clone https://github.com/acmesh-official/acme.sh.git
 143 cd ./acme.sh
 144 ./acme.sh --install -m my@example.com
 145 ```
 146
 147 You `don't have to be root` then, although `it is recommended`.
 148
 149 Advanced Installation: https://github.com/acmesh-official/acme.sh/wiki/How-to-install
 150
 151 The installer will perform 3 actions:
 152
 153 1. Create and copy `acme.sh` to your home dir (`$HOME`): `~/.acme.sh/`.
 154 All certs will be placed in this folder too.
 155 2. Create alias for: `acme.sh=~/.acme.sh/acme.sh`.
 156 3. Create daily cron job to check and renew the certs if needed.
 157
 158 Cron entry example:
 159
 160 ```bash
 161 0 0 * * * "/home/user/.acme.sh"/acme.sh --cron --home "/home/user/.acme.sh" > /dev/null
 162 ```
 163
 164 After the installation, you must close the current terminal and reopen it to make the alias take effect.
 165
 166 Ok, you are ready to issue certs now.
 167
 168 Show help message:
 169
 170 ```sh
 171 root@v1:~# acme.sh -h
 172 ```
 173
 174 # 2. Just issue a cert
 175
 176 **Example 1:** Single domain.
 177
 178 ```bash
 179 acme.sh --issue -d example.com -w /home/wwwroot/example.com
 180 ```
 181
 182 or:
 183
 184 ```bash
 185 acme.sh --issue -d example.com -w /home/username/public_html
 186 ```
 187
 188 or:
 189
 190 ```bash
 191 acme.sh --issue -d example.com -w /var/www/html
 192 ```
 193
 194 **Example 2:** Multiple domains in the same cert.
 195
 196 ```bash
 197 acme.sh --issue -d example.com -d www.example.com -d cp.example.com -w /home/wwwroot/example.com
 198 ```
 199
 200 The parameter `/home/wwwroot/example.com` or `/home/username/public_html` or `/var/www/html` is the web root folder where you host your website files. You **MUST** have `write access` to this folder.
 201
 202 Second argument **"example.com"** is the main domain you want to issue the cert for.
 203 You must have at least one domain there.
 204
 205 You must point and bind all the domains to the same webroot dir: `/home/wwwroot/example.com`.
 206
 207 The certs will be placed in `~/.acme.sh/example.com/`
 208
 209 The certs will be renewed automatically every **60** days.
 210
 211 More examples: https://github.com/acmesh-official/acme.sh/wiki/How-to-issue-a-cert
 212
 213
 214 # 3. Install the cert to Apache/Nginx etc.
 215
 216 After the cert is generated, you probably want to install/copy the cert to your Apache/Nginx or other servers.
 217 You **MUST** use this command to copy the certs to the target files, **DO NOT** use the certs files in **~/.acme.sh/** folder, they are for internal use only, the folder structure may change in the future.
 218
 219 **Apache** example:
 220 ```bash
 221 acme.sh --install-cert -d example.com \
 222 --cert-file      /path/to/certfile/in/apache/cert.pem  \
 223 --key-file       /path/to/keyfile/in/apache/key.pem  \
 224 --fullchain-file /path/to/fullchain/certfile/apache/fullchain.pem \
 225 --reloadcmd     "service apache2 force-reload"
 226 ```
 227
 228 **Nginx** example:
 229 ```bash
 230 acme.sh --install-cert -d example.com \
 231 --key-file       /path/to/keyfile/in/nginx/key.pem  \
 232 --fullchain-file /path/to/fullchain/nginx/cert.pem \
 233 --reloadcmd     "service nginx force-reload"
 234 ```
 235
 236 Only the domain is required, all the other parameters are optional.
 237
 238 The ownership and permission info of existing files are preserved. You can pre-create the files to define the ownership and permission.
 239
 240 Install/copy the cert/key to the production Apache or Nginx path.
 241
 242 The cert will be renewed every **60** days by default (which is configurable). Once the cert is renewed, the Apache/Nginx service will be reloaded automatically by the command: `service apache2 force-reload` or `service nginx force-reload`.
 243
 244
 245 **Please take care:  The reloadcmd is very important. The cert can be automatically renewed, but, without a correct 'reloadcmd' the cert may not be flushed to your server(like nginx or apache), then your website will not be able to show renewed cert in 60 days.**
 246
 247 # 4. Use Standalone server to issue cert
 248
 249 **(requires you to be root/sudoer or have permission to listen on port 80 (TCP))**
 250
 251 Port `80` (TCP) **MUST** be free to listen on, otherwise you will be prompted to free it and try again.
 252
 253 ```bash
 254 acme.sh --issue --standalone -d example.com -d www.example.com -d cp.example.com
 255 ```
 256
 257 More examples: https://github.com/acmesh-official/acme.sh/wiki/How-to-issue-a-cert
 258
 259 # 5. Use Standalone ssl server to issue cert
 260
 261 **(requires you to be root/sudoer or have permission to listen on port 443 (TCP))**
 262
 263 Port `443` (TCP) **MUST** be free to listen on, otherwise you will be prompted to free it and try again.
 264
 265 ```bash
 266 acme.sh --issue --alpn -d example.com -d www.example.com -d cp.example.com
 267 ```
 268
 269 More examples: https://github.com/acmesh-official/acme.sh/wiki/How-to-issue-a-cert
 270
 271
 272 # 6. Use Apache mode
 273
 274 **(requires you to be root/sudoer, since it is required to interact with Apache server)**
 275
 276 If you are running a web server, it is recommended to use the `Webroot mode`.
 277
 278 Particularly, if you are running an Apache server, you can use Apache mode instead. This mode doesn't write any files to your web root folder.
 279
 280 Just set string "apache" as the second argument and it will force use of apache plugin automatically.
 281
 282 ```sh
 283 acme.sh --issue --apache -d example.com -d www.example.com -d cp.example.com
 284 ```
 285
 286 **This apache mode is only to issue the cert, it will not change your apache config files.
 287 You will need to configure your website config files to use the cert by yourself.
 288 We don't want to mess with your apache server, don't worry.**
 289
 290 More examples: https://github.com/acmesh-official/acme.sh/wiki/How-to-issue-a-cert
 291
 292 # 7. Use Nginx mode
 293
 294 **(requires you to be root/sudoer, since it is required to interact with Nginx server)**
 295
 296 If you are running a web server, it is recommended to use the `Webroot mode`.
 297
 298 Particularly, if you are running an nginx server, you can use nginx mode instead. This mode doesn't write any files to your web root folder.
 299
 300 Just set string "nginx" as the second argument.
 301
 302 It will configure nginx server automatically to verify the domain and then restore the nginx config to the original version.
 303
 304 So, the config is not changed.
 305
 306 ```sh
 307 acme.sh --issue --nginx -d example.com -d www.example.com -d cp.example.com
 308 ```
 309
 310 **This nginx mode is only to issue the cert, it will not change your nginx config files.
 311 You will need to configure your website config files to use the cert by yourself.
 312 We don't want to mess with your nginx server, don't worry.**
 313
 314 More examples: https://github.com/acmesh-official/acme.sh/wiki/How-to-issue-a-cert
 315
 316 # 8. Automatic DNS API integration
 317
 318 If your DNS provider supports API access, we can use that API to automatically issue the certs.
 319
 320 You don't have to do anything manually!
 321
 322 ### Currently acme.sh supports most of the dns providers:
 323
 324 https://github.com/acmesh-official/acme.sh/wiki/dnsapi
 325
 326 # 9. Use DNS manual mode:
 327
 328 See: https://github.com/acmesh-official/acme.sh/wiki/dns-manual-mode first.
 329
 330 If your dns provider doesn't support any api access, you can add the txt record by hand.
 331
 332 ```bash
 333 acme.sh --issue --dns -d example.com -d www.example.com -d cp.example.com
 334 ```
 335
 336 You should get an output like below:
 337
 338 ```sh
 339 Add the following txt record:
 340 Domain:_acme-challenge.example.com
 341 Txt value:9ihDbjYfTExAYeDs4DBUeuTo18KBzwvTEjUnSwd32-c
 342
 343 Add the following txt record:
 344 Domain:_acme-challenge.www.example.com
 345 Txt value:9ihDbjxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 346
 347 Please add those txt records to the domains. Waiting for the dns to take effect.
 348 ```
 349
 350 Then just rerun with `renew` argument:
 351
 352 ```bash
 353 acme.sh --renew -d example.com
 354 ```
 355
 356 Ok, it's done.
 357
 358 **Take care, this is dns manual mode, it can not be renewed automatically. you will have to add a new txt record to your domain by your hand when you renew your cert.**
 359
 360 **Please use dns api mode instead.**
 361
 362 # 10. Issue ECC certificates
 363
 364 Just set the `keylength` parameter with a prefix `ec-`.
 365
 366 For example:
 367
 368 ### Single domain ECC certificate
 369
 370 ```bash
 371 acme.sh --issue -w /home/wwwroot/example.com -d example.com --keylength ec-256
 372 ```
 373
 374 ### SAN multi domain ECC certificate
 375
 376 ```bash
 377 acme.sh --issue -w /home/wwwroot/example.com -d example.com -d www.example.com --keylength ec-256
 378 ```
 379
 380 Please look at the `keylength` parameter above.
 381
 382 Valid values are:
 383
 384 1. **ec-256 (prime256v1, "ECDSA P-256", which is the default key type)**
 385 2. **ec-384 (secp384r1,  "ECDSA P-384")**
 386 3. **ec-521 (secp521r1,  "ECDSA P-521", which is not supported by Let's Encrypt yet.)**
 387 4. **2048   (RSA2048)**
 388 5. **3072   (RSA3072)**
 389 6. **4096   (RSA4096)**
 390
 391
 392 # 11. Issue Wildcard certificates
 393
 394 It's simple, just give a wildcard domain as the `-d` parameter.
 395
 396 ```sh
 397 acme.sh  --issue -d example.com  -d '*.example.com'  --dns dns_cf
 398 ```
 399
 400
 401
 402 # 12. How to renew the certs
 403
 404 No, you don't need to renew the certs manually. All the certs will be renewed automatically every **60** days.
 405
 406 However, you can also force to renew a cert:

 408 ```sh

 419 # 13. How to stop cert renewal
 420
 421 To stop renewal of a cert, you can execute the following to remove the cert from the renewal list:
 422
 423 ```sh
 424 acme.sh --remove -d example.com [--ecc]
 425 ```
 426
 427 The cert/key file is not removed from the disk.
 428
 429 You can remove the respective directory (e.g. `~/.acme.sh/example.com`) by yourself.

 432 # 14. How to upgrade `acme.sh`
 433
 434 acme.sh is in constant development, so it's strongly recommended to use the latest code.
 435
 436 You can update acme.sh to the latest code:
 437
 438 ```sh
 439 acme.sh --upgrade
 440 ```
 441
 442 You can also enable auto upgrade:
 443
 444 ```sh
 445 acme.sh --upgrade --auto-upgrade
 446 ```
 447
 448 Then **acme.sh** will be kept up to date automatically.
 449
 450 Disable auto upgrade:
 451
 452 ```sh
 453 acme.sh --upgrade --auto-upgrade 0
 454 ```
