# 10. Issue ECC certificates
-`Let's Encrypt` can now issue **ECDSA** certificates.
-
-And we support them too!
-
Just set the `keylength` parameter with a prefix `ec-`.
For example:
Valid values are:
-1. **ec-256 (prime256v1, "ECDSA P-256")**
+1. **ec-256 (prime256v1, "ECDSA P-256", which is the default key type)**
2. **ec-384 (secp384r1, "ECDSA P-384")**
3. **ec-521 (secp521r1, "ECDSA P-521", which is not supported by Let's Encrypt yet.)**
-
+4. **2048 (RSA2048)**
+5. **3072 (RSA3072)**
+6. **4096 (RSA4096)**
