   4 - An ACME protocol client written purely in Shell (Unix shell) language.
   5 - Full ACME protocol implementation.
   6 - Support ACME v1 and ACME v2
   7 - Support ACME v2 wildcard certs
   8 - Simple, powerful and very easy to use. You only need 3 minutes to learn it.
   9 - Bash, dash and sh compatible.
  10 - Simplest shell script for Let's Encrypt free certificate client.
  11 - Purely written in Shell with no dependencies on python or the official Let's Encrypt client.
  12 - Just one script to issue, renew and install your certificates automatically.
  13 - DOES NOT require `root/sudoer` access.
  14 - Docker friendly
  15 - IPv6 support
  16
  17 It's probably the `easiest & smartest` shell script to automatically issue & renew the free certificates from Let's Encrypt.

  85 # 1. How to install
  86
  87 ### 1. Install online
  88
  89 Check this project: https://github.com/Neilpang/get.acme.sh
  90
  91 ```bash
  92 curl https://get.acme.sh | sh
  93 ```
  94
  95 Or:
  96
  97 ```bash
  98 wget -O -  https://get.acme.sh | sh
  99 ```
 100
 101
 102 ### 2. Or, Install from git
 103
 104 Clone this project and launch installation:
 105
 106 ```bash
 107 git clone https://github.com/Neilpang/acme.sh.git
 108 cd ./acme.sh
 109 ./acme.sh --install
 110 ```
 111
 112 You `don't have to be root` then, although `it is recommended`.
 113
 114 Advanced Installation: https://github.com/Neilpang/acme.sh/wiki/How-to-install
 115
 116 The installer will perform 3 actions:
 117
 118 1. Create and copy `acme.sh` to your home dir (`$HOME`): `~/.acme.sh/`.
 119 All certs will be placed in this folder too.
 120 2. Create alias for: `acme.sh=~/.acme.sh/acme.sh`.
 121 3. Create daily cron job to check and renew the certs if needed.
 122
 123 Cron entry example:
 124
 125 ```bash
 126 0 0 * * * "/home/user/.acme.sh"/acme.sh --cron --home "/home/user/.acme.sh" > /dev/null
 127 ```
 128
 129 After the installation, you must close the current terminal and reopen it to make the alias take effect.
 130
 131 Ok, you are ready to issue certs now.
 132
 133 Show help message:
 134
 135 ```sh
 136 root@v1:~# acme.sh -h
 137 ```
 138
 139 # 2. Just issue a cert
 140
 141 **Example 1:** Single domain.
 142
 143 ```bash
 144 acme.sh --issue -d example.com -w /home/wwwroot/example.com
 145 ```
 146
 147 or:
 148
 149 ```bash
 150 acme.sh --issue -d example.com -w /home/username/public_html
 151 ```
 152
 153 or:
 154
 155 ```bash
 156 acme.sh --issue -d example.com -w /var/www/html
 157 ```
 158
 159 **Example 2:** Multiple domains in the same cert.
 160
 161 ```bash
 162 acme.sh --issue -d example.com -d www.example.com -d cp.example.com -w /home/wwwroot/example.com
 163 ```
 164
 165 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.
 166
 167 Second argument **"example.com"** is the main domain you want to issue the cert for.
 168 You must have at least one domain there.
 169
 170 You must point and bind all the domains to the same webroot dir: `/home/wwwroot/example.com`.
 171
 172 The certs will be placed in `~/.acme.sh/example.com/`
 173
 174 The certs will be renewed automatically every **60** days.
 175
 176 More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
 177
 178
 179 # 3. Install the cert to Apache/Nginx etc.
 180
 181 After the cert is generated, you probably want to install/copy the cert to your Apache/Nginx or other servers.
 182 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.
 183
 184 **Apache** example:
 185 ```bash
 186 acme.sh --install-cert -d example.com \
 187 --cert-file      /path/to/certfile/in/apache/cert.pem  \
 188 --key-file       /path/to/keyfile/in/apache/key.pem  \
 189 --fullchain-file /path/to/fullchain/certfile/apache/fullchain.pem \
 190 --reloadcmd     "service apache2 force-reload"
 191 ```
 192
 193 **Nginx** example:
 194 ```bash
 195 acme.sh --install-cert -d example.com \
 196 --key-file       /path/to/keyfile/in/nginx/key.pem  \
 197 --fullchain-file /path/to/fullchain/nginx/cert.pem \
 198 --reloadcmd     "service nginx force-reload"
 199 ```
 200
 201 Only the domain is required, all the other parameters are optional.
 202
 203 The ownership and permission info of existing files are preserved. You can pre-create the files to define the ownership and permission.
 204
 205 Install/copy the cert/key to the production Apache or Nginx path.
 206
 207 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`.
 208
 209
 210 **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.**
 211
 212 # 4. Use Standalone server to issue cert
 213
 214 **(requires you to be root/sudoer or have permission to listen on port 80 (TCP))**
 215
 216 Port `80` (TCP) **MUST** be free to listen on, otherwise you will be prompted to free it and try again.
 217
 218 ```bash
 219 acme.sh --issue --standalone -d example.com -d www.example.com -d cp.example.com
 220 ```
 221
 222 More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
 223
 224
 225 # 5. Use Apache mode
 226
 227 **(requires you to be root/sudoer, since it is required to interact with Apache server)**
 228
 229 If you are running a web server, Apache or Nginx, it is recommended to use the `Webroot mode`.
 230
 231 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.
 232
 233 Just set string "apache" as the second argument and it will force use of apache plugin automatically.
 234
 235 ```sh
 236 acme.sh --issue --apache -d example.com -d www.example.com -d cp.example.com
 237 ```
 238
 239 **This apache mode is only to issue the cert, it will not change your apache config files.
 240 You will need to configure your website config files to use the cert by yourself.
 241 We don't want to mess your apache server, don't worry.**
 242
 243 More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
 244
 245 # 6. Use Nginx mode
 246
 247 **(requires you to be root/sudoer, since it is required to interact with Nginx server)**
 248
 249 If you are running a web server, Apache or Nginx, it is recommended to use the `Webroot mode`.
 250
 251 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.
 252
 253 Just set string "nginx" as the second argument.
 254
 255 It will configure nginx server automatically to verify the domain and then restore the nginx config to the original version.
 256
 257 So, the config is not changed.
 258
 259 ```sh
 260 acme.sh --issue --nginx -d example.com -d www.example.com -d cp.example.com
 261 ```
 262
 263 **This nginx mode is only to issue the cert, it will not change your nginx config files.
 264 You will need to configure your website config files to use the cert by yourself.
 265 We don't want to mess your nginx server, don't worry.**
 266
 267 More examples: https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert
 268
 269 # 7. Automatic DNS API integration
 270
 271 If your DNS provider supports API access, we can use that API to automatically issue the certs.
 272
 273 You don't have to do anything manually!
 274

 325
 326
 327 **More APIs coming soon...**
 328
 329 If your DNS provider is not on the supported list above, you can write your own DNS API script easily. If you do, please consider submitting a [Pull Request](https://github.com/Neilpang/acme.sh/pulls) and contribute it to the project.
 330
 331 For more details: [How to use DNS API](dnsapi)
 332
 333 # 8. Use DNS manual mode:
 334
 335 See: https://github.com/Neilpang/acme.sh/wiki/dns-manual-mode first.
 336
 337 If your dns provider doesn't support any api access, you can add the txt record by your hand.
 338
 339 ```bash
 340 acme.sh --issue --dns -d example.com -d www.example.com -d cp.example.com
 341 ```
 342
 343 You should get an output like below:
 344
 345 ```sh
 346 Add the following txt record:
 347 Domain:_acme-challenge.example.com
 348 Txt value:9ihDbjYfTExAYeDs4DBUeuTo18KBzwvTEjUnSwd32-c
 349
 350 Add the following txt record:
 351 Domain:_acme-challenge.www.example.com
 352 Txt value:9ihDbjxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 353
 354 Please add those txt records to the domains. Waiting for the dns to take effect.
 355 ```
 356
 357 Then just rerun with `renew` argument:
 358
 359 ```bash
 360 acme.sh --renew -d example.com
 361 ```
 362
 363 Ok, it's done.
 364
 365 **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.**
 366
 367 **Please use dns api mode instead.**
 368
 369 # 9. Issue ECC certificates
 370
 371 `Let's Encrypt` can now issue **ECDSA** certificates.
 372
 373 And we support them too!
 374
 375 Just set the `keylength` parameter with a prefix `ec-`.
 376
 377 For example:
 378
 379 ### Single domain ECC certificate
 380
 381 ```bash
 382 acme.sh --issue -w /home/wwwroot/example.com -d example.com --keylength ec-256
 383 ```
 384
 385 ### SAN multi domain ECC certificate
 386
 387 ```bash
 388 acme.sh --issue -w /home/wwwroot/example.com -d example.com -d www.example.com --keylength ec-256
 389 ```
 390
 391 Please look at the `keylength` parameter above.
 392
 393 Valid values are:
 394
 395 1. **ec-256 (prime256v1, "ECDSA P-256")**
 396 2. **ec-384 (secp384r1,  "ECDSA P-384")**
 397 3. **ec-521 (secp521r1,  "ECDSA P-521", which is not supported by Let's Encrypt yet.)**
 398
 399
 400
 401 # 10. Issue Wildcard certificates
 402
 403 It's simple, just give a wildcard domain as the `-d` parameter.
 404
 405 ```sh
 406 acme.sh  --issue -d example.com  -d '*.example.com'  --dns dns_cf
 407 ```
 408
 409
 410
 411 # 11. How to renew the certs
 412
 413 No, you don't need to renew the certs manually. All the certs will be renewed automatically every **60** days.
 414
 415 However, you can also force to renew a cert:
 416
 417 ```sh
 418 acme.sh --renew -d example.com --force
 419 ```
 420
 421 or, for ECC cert:
 422
 423 ```sh
 424 acme.sh --renew -d example.com --force --ecc
 425 ```
 426
 427
 428 # 12. How to stop cert renewal
 429
 430 To stop renewal of a cert, you can execute the following to remove the cert from the renewal list:
 431
 432 ```sh
 433 acme.sh --remove -d example.com [--ecc]
 434 ```
 435
 436 The cert/key file is not removed from the disk.
 437
 438 You can remove the respective directory (e.g. `~/.acme.sh/example.com`) by yourself.
 439
 440
 441 # 13. How to upgrade `acme.sh`
 442
 443 acme.sh is in constant development, so it's strongly recommended to use the latest code.
 444
 445 You can update acme.sh to the latest code:
 446
 447 ```sh
 448 acme.sh --upgrade
 449 ```
 450
 451 You can also enable auto upgrade:
 452
 453 ```sh
 454 acme.sh --upgrade --auto-upgrade
 455 ```
 456
 457 Then **acme.sh** will be kept up to date automatically.
 458
 459 Disable auto upgrade:
 460
 461 ```sh
 462 acme.sh --upgrade --auto-upgrade 0
 463 ```
