ssl-ciphers

List of cipher suites used for encryption

Syntax

--ssl-ciphers ciphers

Description

ssl-ciphers provides a list of cipher suites that the server uses for encryption.

Parameters

ciphers

Cipher suites the server instance uses for encryption. Valid values are:

  • ALL — Use all available cipher suites except eNULL.

  • HIGH — Use all available high encryption cipher suites.

  • list — Comma-separated list of cipher suites to use.

All OpenSSL configuration strings can be passed with the ciphers. This provides finer control over the selected cipher.

Examples

Use only high encryption cipher suites.

--ssl-ciphers HIGH

Disable the use of ADH ciphers.

--ssl-ciphers ALL:!ADH

Use the strongest available ECDHE ciphers.

--ssl-ciphers ALL:@STRENGTH

Disable the use of ADH ciphers and use the strongest available ECDHE ciphers.

--ssl-ciphers ALL:!ADH@STRENGTH
