The following ciphers are allowed in dotConnect for PostgreSQL:
You can use ALL keyword to indicate whole set of ciphers. To exclude certain cipher from the set use "-" sign. For instance, value of SslCipherList property "ALL-RC4" means that any cipher but RC4 can be used.
You can control performance-security trade-off using this property. To gain better performance you can use RC2 cipher. To achieve maximal traffic security you can use 3DES or AES ciphers.
