Here’s a breakdown of what each part represents in this hash format:

pbkdf2_sha256: This is the hashing algorithm used, PBKDF2 (Password-Based Key Derivation Function 2) with SHA-256 as the underlying hash function.

150000: This is the number of iterations. In this case, the password has been hashed 150000 times to increase security. More iterations make the hashing process more secure by making it slower to crack, though also more computationally intensive.

O9hNDLwzBc7r: This is the salt. A salt is a random value added to the password before hashing, preventing the use of precomputed hash tables (like rainbow tables) to reverse-engineer the original password.

RzJPG76Vki36xEflUPKn37jYI3xRbbf6MTPrWbjFrgQ=: This is the resulting hashed password.
