Maybe you could Google for "ciphers" iso "chipers" and have better results.

First hit for "openssl ciphers"

# default 512-bit key, sent to standard output openssl genrsa

# 1024-bit key, saved to file named mykey.pem openssl genrsa -out mykey.pem 1024

# same as above, but encrypted with a passphrase openssl genrsa -des3 -out mykey.pem 1024 Received on Sat Oct 29 2011 - 06:58:15 CDT
