bool ccf::kv::TxEncryptor< T, S >::decrypt	(	const std::vector< uint8_t > &	cipher,

Decrypt cipher and return plaintext.

Parameters

[in]	cipher	Cipher to decrypt
[in]	additional_data	Additional data to verify tag
[in]	serialised_header	Serialised header (iv + tag)
[out]	plain	Decrypted plaintext
[in]	version	Version used to retrieve the corresponding encryption key
[out]	term	Term contained in header
[in]	historical_hint	If true, considers all ledger secrets for decryption. Otherwise, try to use the latest used secret (defaults to false)

	)

inlineoverridevirtual

Encrypt data and return serialised GCM header and cipher.

Parameters

[in]	plain	Plaintext to encrypt
[in]	additional_data	Additional data to tag
[out]	serialised_header	Serialised header (iv + tag)
[out]	cipher	Encrypted ciphertext encryption key
[in]	tx_id	Transaction ID (version + term) corresponding with the plaintext
[in]	entry_type	Indicates the type of the entry to avoid IV re-use
[in]	historical_hint	If true, considers all ledger secrets for encryption. Otherwise, try to use the latest used secret (defaults to false)
