PGP [1024-bit] digital signature vs SHA256 HMAC Comparison... First, you can compare asymmetric and symmetric algorithms. A 1024-bit asymmetric key provides about 80-bits of security. A SHA256 HMAC provides about 128-bits of security. With all other things being equal, the HMAC is stronger. Second, I believe PGP (or is it GnuPG) uses Lim-Lee primes and ...


Questions like these are hard to answer because who can predict what the future holds, right? That said, there are some things I wanted to share. Prefer symmetric cryptography over public-key cryptography. Prefer conventional discrete-log-based systems over elliptic-curve systems; the latter have constants that the NSA influences when they can. From NSA ...
