Understanding Cryptographic Hashing
A cryptographic hash function transforms any input into a fixed-size string of characters (the hash digest). The same input always produces the same output, but even a tiny change in input produces a completely different hash. Hashes are one-way functions — you cannot reverse a hash to recover the original input.
Common uses include password storage, data integrity verification, digital signatures, and checksums. This tool uses the Web Crypto API built into your browser, ensuring all computation is secure, private, and performed client-side.
