How to Use
Type or paste any text into the input field. SHA-1, SHA-256, and SHA-512 hashes are computed automatically as you type. Click any hash result to copy it to your clipboard.
What is a Cryptographic Hash?
A cryptographic hash function takes an input of arbitrary length and produces a fixed-size string of characters. The same input always yields the same hash, but even a tiny change in the input produces a completely different output. Hashes are one-way — you cannot recover the original text from a hash.
SHA Algorithms
SHA-1 produces a 160-bit (40 hex character) digest. It is considered weak for security purposes but still useful for checksums and legacy compatibility.SHA-256 and SHA-512 are part of the SHA-2 family and are widely used for password storage, digital signatures, blockchain, and data integrity verification.
Client-Side & Secure
This tool uses the browser's native crypto.subtle.digest Web Crypto API. All hashing happens locally in your browser — your data is never sent to any server. Note that MD5 is not available through the Web Crypto API and is omitted here; use SHA-256 or SHA-512 for modern security needs.
