Hash Algorithm From the pull-down menu, select one of the following hash algorithms:
• MD5. A 128 bit (16 byte) message digest, slightly faster than SHA-1.
• SHA-1. A 160-bit (20 byte) message digest, slightly stronger than MD5
Signature Algorithm Although this seems to be a pull-down menu, the only possible selection is
RSA. In other words, RSA is the default to generate a CSR.
Signature Key Length From the pull-down menu, select one of the following signature key lengths
in bits:
• 512.
• 1024.
• 2048.
Note: Larger key sizes might improve security, but might also decrease
performance.
