💡 About Cryptographic Hashes

Cryptographic hash functions convert data into fixed-size strings. They are one-way functions, meaning you cannot reverse them to get the original data.

Algorithm Comparison:
●
MD5: 128-bit, deprecated for security
●
SHA-1: 160-bit, deprecated for security
●
SHA-256: 256-bit, recommended
●
SHA-512: 512-bit, maximum security
Common Use Cases:
  • Password storage (with salt)
  • File integrity verification
  • Digital signatures
  • Blockchain technology
  • Data deduplication
  • Message authentication (HMAC)
HMAC (Hash-based Message Authentication Code):

HMAC combines a cryptographic hash function with a secret key to provide message authentication. It's used to verify both data integrity and authentication.
