Hash Calculator

Enter text to get five hashes at once. MD5 and SHA-1 are explicitly marked insecure — they still compute, but should not be used.

Notes

A hash is not encryption and cannot be reversed — but it is not a password storage scheme either; use bcrypt/argon2 for that.
Text is hashed as UTF-8 bytes, matching command-line sha256sum.
MD5 has practical collisions and SHA-1 is broken (SHAttered); neither should be used for signatures or integrity checks.
