WebPGP [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. WebJun 8, 2024 · Encryption; Signatures; Hashing Hashing can be simply explained as translation from input text into resulting text of fixed size by use of the algorithm. As you can see in above examples with just a slight change of input text, result will be completely different. Let's take a look at an example in .Net Core with use of SHA-256 algorithm.
