Hash Generator

Generate MD5, SHA1, SHA256, and SHA512 hashes for any text instantly.

Examples

File integrity: compare a known SHA256 hash against a downloaded file’s hash (use a local tool to hash the file).
Deduping strings: hash IDs/emails to compare lists without storing raw values (still be careful with privacy).
API signatures: generate a digest for debugging when a system expects a hash.

FAQ

Is hashing encryption?
No. Hashing is one-way. You generally can’t recover the original input from a secure hash.

Should I use MD5 or SHA1?
For security-sensitive uses, prefer SHA256/SHA512. MD5/SHA1 are considered weak for collision resistance.

Is my text uploaded?
This tool uses an API to compute hashes. Avoid hashing sensitive secrets here; use local tools if you need privacy.

Security note

Hashes are not a safe way to “hide” secrets. If you need to store passwords, use a dedicated password-hashing function with a salt (for example, bcrypt/argon2) rather than a fast hash like SHA256.
