MD5 is faster but cryptographically broken and insecure. SHA-256 is slower but secure and recommended for cryptographic purposes. MD5 should only be used for checksums, not security.
For security: SHA-256 or SHA-512. For checksums: MD5 or SHA-1 (though SHA-1 is deprecated). For modern applications, SHA-256 is the standard choice.
Yes! You can upload files to generate their hash. This is useful for verifying file integrity, detecting duplicates, or creating checksums.
SHA-3 is the latest SHA standard, based on the Keccak algorithm. It offers different security properties than SHA-2 and is a good alternative for modern applications.
