 == Authentication Application ==
 The authentication application does not expose the result of the encryption. Instead, the result is used only in authentication mode, where the following operations are performed:
-# Load encryption key with 'k' command (for example, k2b7e151628aed2a6abf7158809cf4f3c\n sets key to k2b7e151628aed2a6abf7158809cf4f3c).

 # Set the authentication challenge with 't' command.
 # Set input text to encryption module with 'p' command. Device encrypts input text, and toggles the I/O trigger line during the encryption operation.

 == Encryption Application ==
 The encryption application provides a simple method to encrypt a plaintext into a ciphertext. This application was the original "simple serial". The following operations are performed:
-# Load encryption key with 'k' command (for example, k2b7e151628aed2a6abf7158809cf4f3c\n sets key to k2b7e151628aed2a6abf7158809cf4f3c).

 # Set input text to encryption module with 'p' command. Device encrypts input text, and toggles the I/O trigger line during the encryption operation.
 # The ciphertext is returned with the 'r' command.
