Abstract
Examples discussed herein disclose, among other things, an encrypting device. The encrypting device may include a format preserving encryptor to obtain a plaintext, obtain a key from a plurality of keys stored in a key database, and encrypt the plaintext using the key to produce a ciphertext having a length of the plaintext. The encrypting device may also include a key reference embedder to obtain a key reference associated with the key, and generate an extended ciphertext by adding to the ciphertext a set of characters associated with the key reference, such that the key reference can be determined based on the extended ciphertext.
