What salt is used with SHA-256 password encryption?

[Jostein Baustad, geändert vor 12 Jahren.]

Does Liferay password encryption algorithm SHA-256 use a salt? If yes, how is the salt generated and what is the size?

passwords.encryption.algorithm=SHA-256

Looking at the code, PwdEncryptor.encodePassword() doesn't seem to be using seed when algorithm is SHA-256.
