Abstract

A system and method for cryptography. The system may include a cryptography module in communication with a database and configured to perform cryptography operations on data in the database, a rotation module configured to rotate data in the database, and one or more application interfaces configured to remain responsive while the rotation module rotates the data in the database. Rotating the data in the database may include decrypting a stored value in a system with a first key to produce a decrypted value, encrypting the decrypted value with a second key to produce an encrypted value, and replacing the stored value with the encrypted value.
