Hash generator
Create a fixed-length digest from text.
One-way transformations
Hash Tools
Generate message digests and identify likely hash formats. Hashes are one-way; there is no such thing as a legitimate “hash decoder.”
Hash identifier
Guess likely types from length and character pattern.
Possible formats will appear here.
Salts
A unique random salt makes identical passwords produce different hashes and frustrates precomputed attacks.
Collision resistance
It should be computationally impractical to find two different inputs with the same digest.
Preimage resistance
Given a digest, finding any original input that produced it should be impractical.
Password storage
Use dedicated, slow password hashing functions such as Argon2id, scrypt, bcrypt, or PBKDF2—not a fast general-purpose hash alone.
Weak algorithms
MD5 and SHA-1 have practical collision weaknesses and should not protect signatures, certificates, or other security-sensitive data. They remain here for compatibility and recognition exercises.
