Password4j is a Java user-friendly cryptographic library for hashing and checking passwords
with different
Key derivation functions (KDFs) and Cryptographic hash functions (CHFs).
You can hash passwords with
PBKDF2
bcrypt
scrypt
Argon2
Use Password4j when you need to
- Use the most modern and secure hashing cryptographic functions
- Change the configuration of the algorithm without your users having to reset their password
- Keep your application OS-independent (e.g. you don't want to rely on JNI)
- Choose the algorithms' parameters depending on your system capabilities
- Make your application using unsecure hashing functions (like MD5 or SHA) compliant to organizational standards
