Generate cryptographic hashes from strings. Output is a lowercase hex string.

Input Text

SHA-256 Hash

Cryptographic Hashes

Hashing is a one-way mathematical function that converts data of any size to a fixed-size string. A small change in the input produces a significantly different output hash.

While MD5 and SHA-1 are common for checksums and basic integrity checks, they are considered vulnerable to collision attacks. SHA-256 or higher is recommended for modern security needs.
