About Hash Algorithms

Hash functions generate fixed-size fingerprints of data. Each algorithm produces a unique hash value that represents the input data, with different output sizes and security characteristics.

MD5 (128-bit):

Fast but cryptographically broken. Use only for checksums and non-security purposes.

SHA-1 (160-bit):

Deprecated for security applications due to known vulnerabilities.

SHA-256 (256-bit):

Secure modern standard. Recommended for most cryptographic applications.

SHA-512 (512-bit):

Highest security level. Ideal for sensitive cryptographic operations.
