About this tool
Compute SHA-1, SHA-256, and SHA-512 cryptographic hashes entirely in your browser using the Web Crypto API. No data is ever sent to a server. Use it to verify file integrity or generate checksums for any text input.
Frequently Asked Questions
What is the difference between SHA-1, SHA-256, and SHA-512?
SHA-1 produces a 160-bit hash and is considered weak for security use. SHA-256 and SHA-512 are part of the SHA-2 family and are widely used in TLS and code signing.
Is my input data safe?
Yes. All hashing is performed in your browser using the Web Crypto API. Your input never leaves your device.
Can I reverse a hash back to the original text?
No. SHA hashes are one-way functions. It is computationally infeasible to reverse a SHA-256 or SHA-512 hash.
