    • DEFAULT_TOKEN_BYTE_LENGTH

      public static final int DEFAULT_TOKEN_BYTE_LENGTH
      See tokenByteLength. 8 bytes (64 bits) would be enough, but we want to get padding-less Byte64 representation, so we take the next greater number divisible by 3 which is 9. 9 bytes is equal to 72 bits.
      See Also:

    • tokenByteLength

      protected final int tokenByteLength
      The number of random bits generared by nextRandom(). Use values divisible by 3 to produce random strings consisting only of 0-9, a-z, A-Z, - and _, i.e. URL safe Byte64 without padding. If a value not divisible by 3 is used the random strings will contain * in addition to the named characters.

    • validateToken

      public String validateToken(String stringKey, boolean remove)
      Description copied from interface: TokenStore
      Validates a token. If the token is valid it returns the attached credentials. The store state may be modified by the removal of the token. The token is removed either if the remove argument is set to true of if the token is not anymore valid.
      Specified by:
      validateToken in interface TokenStore
      Parameters:
      stringKey - the token key
      remove - true if the token must be removed regardless its validity
      Returns:
      the attached credentials or null
