Configuration
Configuration for token manager.
The interval to generate a new secret and remove the oldest one in seconds.
tokenLifetime :: Config -> Int #
The token lifetime, that is, tokens can be decrypted in this period.
defaultConfig :: Config #
Default configuration to update secrets in 30 minutes (1,800 seconds) and token lifetime is 2 hours (7,200 seconds)
>>>defaultConfigConfig {interval = 1800, tokenLifetime = 7200}
Token manager
data TokenManager #
The abstract data type for token manager.
spawnTokenManager :: Config -> IO TokenManager #
Spawning a token manager.
killTokenManager :: TokenManager -> IO () #
Killing a token manager.
Encryption and decryption
encryptToken :: TokenManager -> ByteString -> IO ByteString #
Encrypting a target value to get a token.
decryptToken :: TokenManager -> ByteString -> IO (Maybe ByteString) #
Decrypting a token to get a target value.
