where C: AsRef<[u8]>,

Like decrypt but doesn’t expect all values to be decryptable. This only means that a given input is None or the slice is not a serialized EncryptedRecord. In the future this could also cover cases where the caller is not authorized to decrypt a given value.

As it stands, this function will return an Error if any valid ciphertexts fail to decrypt.

Items in the returned vec wil be in the same order as the input but any values that are unable to be decrypted will be returned as None.

Encrypted records must be encoded with hex.
