the plaintext to encrypt
the encryption key to use as an input to the HKDF function which is used to derive the AES key for encryption. Obviously, the same key must be provided when decrypting.
the name of the secret. Used as an input to the HKDF operation which is used to derive the AES key, so again the same value must be provided when decrypting.
Optional
ivStr: stringthe base64-encoded initialization vector to use. If not supplied, a random one will be generated.
The encrypted result, including the ciphertext itself, the initialization vector (as supplied in ivStr
,
or generated), and an HMAC on the ciphertext — all base64-encoded.
Encrypt a string as a secret storage item, using AES-CTR.
