introduce methods for transit API interaction

[stklcode]

Introduce new methods to use hashing and de-/encryption with Vault's transit engine¹.

Encrypt binary or base64 encoded data

connector.transitEncrypt("my-key", "dGVzdA==");
connector.transitEncrypt("my-key", new byte[]{74, 65, 73, 74});

Decrypt

connector.transitDecrypt("my-key", "vault:v1:oWRLHHjAgjPIrY9cYwIV3BRBO665qVYjSK4roVWFwbG8jgdN")

Hash

connector.transitHash("sha2-512", "dGVzdA==");
connector.transitHash("sha2-512", "dGVzdA==", "hex");  // default
connector.transitHash("sha2-512", "dGVzdA==", "base64");
connector.transitEncrypt("sha2-512", new byte[]{74, 65, 73, 74}, "hex");

Response object (relevant part)

{
  "ciphertext": "...",  // filled on encryption
  "plaintext": "...",   // filled on decryption
  "sum": "..."          // filled on hashing
}
