Password storage (FREE)
GitLab stores user passwords in a hashed format to prevent passwords from being stored as plain text.
GitLab uses the Devise authentication library to hash user passwords. Created password hashes have these attributes:
- Hashing: The
bcrypt
hashing function is used to generate the hash of the provided password. This is a strong, industry-standard cryptographic hashing function. - Stretching: Password hashes are stretched to harden against brute-force attacks. By default, GitLab uses a stretching factor of 10.
- Salting: A cryptographic salt is added to each password to harden against pre-computed hash and dictionary attacks. To increase security, each salt is randomly generated for each password, with no two passwords sharing a salt.
