Generate MD5, SHA-1, SHA-256, and SHA-512 hashes from any text.
Pro includes file hashing, batch processing, hash comparison, and checksum verification tools.
A hash is a fixed-size string generated from input data using a mathematical function. The same input always produces the same hash, but it's virtually impossible to reverse a hash back to the original data.
SHA-256 is recommended for most purposes. MD5 and SHA-1 are considered cryptographically weak and should not be used for security. SHA-512 provides the highest security.
