This is a Swift implementation of bcrypt that only relies on Foundation.
/// given a plaintext password, return the password hash
func hashMyPassword(password: String) throws -> String {
// It's this easy
let hashedPassword = try Bcrypt.hashPassword(password: password, rounds: 4)
return hashedPassword
}
/// Check to see if a password matches the password hash
func checkMyPassword(password: String, passwordHash: String) throws -> Bool {
return try Bcrypt.verifyPassword(password: password, hash: passwordHash)
}If an error is thrown it will be of this type:
public enum BcryptError: Error {
/// Rounds was less than 4 or more than 31
case invalidRounds
/// The salt was incorrectly formatted
case invalidSalt
}This is very open source. It is based on work by Felipe Florencio Garcia that is based on work by Jay Fuerstenberg that is based on work by Damien Miller.
