• 4096: 4096-bit keys are accepted by nearly all RSA
systems. Using 4096-bit keys will dramatically increase
generation time, TLS handshake delays, and CPU usage
for TLS operations.
Digest Algorithm
Choose the digest algorithm:
• SHA1: This digest algorithm provides a 160-bit fingerprint

function – it cannot be decrypted back.
