WebSecond, note that base64 character represents 6 bits. This mean that the first 4 base64 characters encodes the first 3 bytes of plaintext, i.e, the 3 first characters (since 4*6 = 3*8). The next 4 base64 characters will then encode the next 3 characters of plaintext and so on. Using this observation it is easy to do frequency analysis. 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.
