Member Data Documentation

n

optional int32 Response_PasswordSalt::n = 2

scrypt cost parameters for the verifier. Absent/zero for legacy accounts.

needs_migration

optional bool Response_PasswordSalt::needs_migration = 6

True when the account still uses the legacy password format and should be migrated to the scrypt format after a successful login.

nonce

optional bytes Response_PasswordSalt::nonce = 5

Server-generated challenge. When present the client must authenticate with a challenge-response instead of transmitting the password hash.

p

optional int32 Response_PasswordSalt::p = 4

password_salt

optional string Response_PasswordSalt::password_salt = 1

Salt for the legacy password hash. Pre-challenge clients derive and send that hash from it. For migrated accounts holding a fresh legacy backup this carries the backup's salt so those clients can still log in; clients that speak challenge-response must use scrypt_salt instead when present.

r

optional int32 Response_PasswordSalt::r = 3

scrypt_salt

optional string Response_PasswordSalt::scrypt_salt = 7

Salt of the stored scrypt verifier. Present for migrated accounts; challenge-response clients derive the verifier from this rather than from password_salt, which may carry a legacy backup salt.
