Hash Generator

Produce cryptographic hashes (MD5, SHA families) with selectable output encodings.

Input Text

Enter the text to hash

MD5
md5

128-bit hash, fast but not cryptographically secure

SHA-1
sha1

160-bit hash, deprecated for security use

SHA-256
sha256

256-bit hash, widely used and secure

SHA-512
sha512

512-bit hash, highest security and performance

About Hash Functions

Hash functions are one-way cryptographic primitives that take input data and produce a fixed-size output (the hash). They're used for data integrity verification, password storage, and digital signatures.

Security Notes: MD5 and SHA-1 are deprecated for security applications due to collision vulnerabilities. Use SHA-256 or SHA-512 for new security implementations.
