WebThe returned ciphertext starts with vault:v1:.The first prefix (vault) identifies that it has been wrapped by Vault.The v1 indicates the key version 1 was used to encrypt the plaintext; therefore, when you rotate keys, Vault knows which version to use for decryption. The rest is a base64 concatenation of the initialization vector (IV) and ciphertext.
