# Encryption

A random secret key is generated to encrypt content, which is shared between wallet client A (i.e. sender) and wallet client B (i.e. receiver). Content is encrypted with AES encryption (i.e. Advanced Encryption Standard). The receiver obtains the secret key from a sender using external communication (i.e. email, chat…) to decrypt the content.
