@ -310,6 +310,42 @@ The following configuration set `Content-Type: application/vnd.android.package-a
- `REDIRECT_OTHER_PORT`: **false**: If true and `PROTOCOL` is https, allows redirecting http requests on `PORT_TO_REDIRECT` to the https port Gitea listens on.
- `PORT_TO_REDIRECT`: **80**: Port for the http redirection service to listen on. Used when `REDIRECT_OTHER_PORT` is true.
- `SSL_MIN_VERSION`: **TLSv1.2**: Set the minimum version of ssl support.
- `SSL_MAX_VERSION`: **\<empty\>**: Set the maximum version of ssl support.
- `SSL_CURVE_PREFERENCES`: **X25519,P256**: Set the prefered curves,
- `SSL_CIPHER_SUITES`: **ecdhe_ecdsa_with_aes_256_gcm_sha384,ecdhe_rsa_with_aes_256_gcm_sha384,ecdhe_ecdsa_with_aes_128_gcm_sha256,ecdhe_rsa_with_aes_128_gcm_sha256,ecdhe_ecdsa_with_chacha20_poly1305,ecdhe_rsa_with_chacha20_poly1305**: Set the preferred cipher suites.
- If there is not hardware support for AES suites by default the cha cha suites will be preferred over the AES suites
- supported suites as of go 1.17 are:
- TLS 1.0 - 1.2 cipher suites
- "rsa_with_rc4_128_sha"
- "rsa_with_3des_ede_cbc_sha"
- "rsa_with_aes_128_cbc_sha"

- Aliased names
- "ecdhe_rsa_with_chacha20_poly1305" is an alias for "ecdhe_rsa_with_chacha20_poly1305_sha256"
- "ecdhe_ecdsa_with_chacha20_poly1305" is alias for "ecdhe_ecdsa_with_chacha20_poly1305_sha256"
- `ENABLE_LETSENCRYPT`: **false**: If enabled you must set `DOMAIN` to valid internet facing domain (ensure DNS is set and port 80 is accessible by letsencrypt validation server).
By using Lets Encrypt **you must consent** to their [terms of service](https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf).
- `LETSENCRYPT_ACCEPTTOS`: **false**: This is an explicit check that you accept the terms of service for Let's Encrypt.
