Years when by and the requirements called for encrypting data in transit while the data at rest was left raw. Encrypting data in transit could be performed by using HTTPS, secure sockets or encrypting the data when retrieved from the servers and decrypting by clients when received. Storing data would be the opposite. The initial decision, given that the client and server where under control, was to encrypt transmissions using the Advanced Encryption Standard (AES) which was designed by Vincent Rijmen and Joan Daemen back in 1998.
