What is hashing?
A hash function takes input data and produces a fixed-length digest. It is commonly used for data integrity verification, checksums and password storage.
Important
Hash is not encryption. MD5 and SHA-1 are not recommended for security-critical password storage. Use SHA-256 or stronger.
Privacy
All hashing is performed locally using the Web Crypto API. Your data never leaves your browser.
FAQ
Is hashing the same as encryption?
No. Hashing is a one-way function. You cannot reverse a hash back to the original data.
Is MD5 secure?
MD5 is considered cryptographically broken. Use SHA-256 or SHA-512 for security-critical applications.
Is my data uploaded?
No. Hashes are computed locally using the Web Crypto API in your browser.
