About SHA-256
SHA-256 (Secure Hash Algorithm 256-bit) is part of the SHA-2 family of cryptographic hash functions. It produces a 256-bit (32-byte) hash value, commonly represented as a 64-character hexadecimal string.
Computationally infeasible to find two different inputs that produce the same hash
Cannot reverse-engineer the original input from the hash output
Always produces a 256-bit output regardless of input size
SHA-256 is a cryptographic hash function that produces a fixed 256-bit fingerprint of any input - widely used for data integrity verification, digital signatures, and blockchain systems. Unlike MD5, SHA-256 remains cryptographically strong and is still trusted for security-relevant hashing (though still not intended for password storage on its own).
Frequently asked questions
SHA-256 alone is fast, which makes it less ideal specifically for password storage compared to purpose-built slow algorithms like BCrypt or Argon2 - SHA-256 is best suited for data integrity checks and general cryptographic hashing rather than passwords directly.
Yes - unlike BCrypt (which salts automatically), SHA-256 is deterministic: the exact same input will always produce the exact same output hash.
Verifying file integrity (checksums), digital signatures, certificate fingerprints, and as a building block in blockchain/cryptocurrency systems.
