Answers to Questions (FAQ)
What is PBKDF2? (Definition)
PBKDF2 (for Password-Based Key Derivation Function 2) is a password-based key derivation algorithm. It is often used to store passwords securely.
How to encrypt using PBKDF2?
PBKDF2 takes a password and salt/salt (a random string of characters) as input, then applies a hash function (usually SHA-1, SHA-256, or SHA-512) iteratively (the number of iterations /rounds is configurable).
Example: PBKDF2() function with sha256 algorithm for password password with salt salt and 1000 iterations returns ba10bd7df33a80626ef566c768b6437f6080cc587e53cbbb297bf009eb31c631
How to decrypt PBKDF2?
The only way to decipher a hash encoded by PBKDF2 is therefore to try all the passwords, with all the salts.
Since this work is gigantic and endless (several years) with a sufficiently long salt chain and a large number of iterations, dCode does not offer this functionality.
How to recognize a PBKDF2 ciphertext? (Identification)
The data generated by PBKDF2 is binary, often stored as hexadecimal values whose length depends on the algorithm used.
The Python library Passlib offers a storage format: $pbkdf2-algo$rounds$salt_b64$hash_b64
The Django CMS uses a similar format: pbkdf2_algo$rounds$salt$hash_b64
