How it works
Computes cryptographic hash digests using MD5, SHA-1, SHA-256, SHA-384, or SHA-512. Uses the native Web Crypto API for SHA variants and a pure-JS implementation for MD5.
Step by step
- 1Enter the text you want to hash.
- 2Select the algorithm: SHA-256 or SHA-512 for security-sensitive use cases.
- 3Choose hex or Base64 output format.
- 4The hash is computed instantly in your browser — input never leaves your device.
Examples
SHA-256 of "Hello, World!"
SHA-256 produces a 64-character hex string (256 bits).

Frequently asked questions
Which hash algorithm should I use?▾
Use SHA-256 or SHA-512 for security-critical applications. MD5 and SHA-1 are cryptographically broken and should only be used for checksums, not security.
Is my data sent to a server?▾
No. All hashing is performed locally in your browser using the Web Crypto API. Your input never leaves your device.
