However, recent advances in cryptanalysis have led to the failure of these hash functions in preserving the strongest property called collision resistance. Factors contributing to the failure are a mathematical weakness found in the Boolean functions used by these cryptographic hash functions, linear ...

New proofs for NMAC and HMAC: security without collision-resistance Cryptographic hash functions are an important tool in cryptography for applications such as digital fingerprinting of messages, message authentication, and key derivation. During the last five years, several fast software hash functions ...
If you decide to avoid MD5 in favor of a SHA algorithm, it is recommended to use SHA-1 over SHA-256 (or higher) because of storage requirements. SHA-1 already provides superior resistance against collisions, which makes SHA-256 in most if not all cases irrelevant. For that reason, ...
