Detailed Description

TpmKeyHandle is an abstract base class for a TPM key handle, which provides an interface to perform cryptographic operations with a key in the TPM.

Member Function Documentation

Blob ndn::TpmKeyHandle::decrypt	(	const uint8_t *	cipherText,
		size_t	cipherTextLength
	)		const

Return the plain text which is decrypted from cipherText using this key.

Parameters

cipherText	The cipher text byte array.
cipherTextLength	The length of the cipher text byte array.

Returns

The decrypted data.

Blob ndn::TpmKeyHandle::derivePublicKey

(

)

const

Get the encoded public key derived from this key.

Returns

The public key encoding Blob.

Blob ndn::TpmKeyHandle::sign	(	DigestAlgorithm	digestAlgorithm,
		const uint8_t *	data,
		size_t	dataLength
	)		const

Compute a digital signature from the byte array using this key with digestAlgorithm.

Parameters

digestAlgorithm	The digest algorithm.
data	The input byte array.
dataLength	The length of the byte array.

Returns

The signature Blob, or an isNull Blob for an unrecognized digestAlgorithm.
