Choose the key length for generating the client certificate.
Following values are available:
•
1024: 1024-bit keys are no longer sufficient to protect
against attacks. Not recommended.
•
2048: 2048-bit keys are a good minimum. Recommended.
•
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.
Choose the digest algorithm:
•
SHA1: This digest algorithm provides a 160-bit fingerprint
output based on arbitrary length input.
•
SHA-256: This digest algorithm generates an almost-
unique, fixed size 256-bit (32-byte) hash. Hash is a one-way
function – it cannot be decrypted back
