Security recommendations

• Prefer newer key exchange and MAC algorithms with SHA-2 variants
• Avoid older algorithms like SHA-1 and MD5 when possible
• Use AES-CTR or AES-CBC modes with 256-bit keys for enhanced security
• Disable weak ciphers like arcfour and 3des if not required by legacy systems

Note

Actual supported algorithms may vary based on specific server configuration and security policy.
