Generate cryptographic hashes using MD5, SHA-1, SHA-256, SHA-384, or SHA-512. All processing happens locally in your browser for complete privacy.
All hashing is done locally in your browser. Your data never leaves your device.
Hash is generated automatically as you type. No need to click a button.
A hash function is a mathematical algorithm that transforms any input data into a fixed-size string of characters, called a hash or digest. This process is one-way—it's computationally infeasible to reverse a hash back to the original input. Hash functions are fundamental to data integrity verification, password storage, and digital signatures.
MD5 produces a 128-bit hash (32 hex characters) but is considered cryptographically broken for security purposes. SHA-1 produces a 160-bit hash and is also deprecated for security. SHA-256 and SHA-512 are part of the SHA-2 family and remain secure for most applications. All hashing is performed locally in your browser—your data never leaves your device.
