Function Documentation

CPKIFCredentialPtr _MakeCredentialFromP8File

(

const std::string &

file

)

Interface: Module

This function creates a CPKIFCredential object from a file containign PKCS8 object

Returns:

A smart pointer to CPKIFCredential obejct

Parameters:

file	[in] String containing the location of PKCS8 file

CPKIFBufferPtr DeriveKeyFromSecret	(	const CPKIFBufferPtr &	secret,
		const CPKIFBufferPtr &	sharedInfo,
		unsigned int	keyLength
	)

Interface: External

Derives a symmetric key from secret and non-secret data.

If length is 0, sharedInfo must be a DER-encoded ECC CMS Shared Info buffer

Returns:

a buffer containing a secret key

Parameters:

secret	[in] shared secret from a key agreement operation
sharedInfo	[in] shared info to append to the hashed data
keyLength	[in] length of the key to derive. If keyLength is 0, sharedInfo must be an ECC CMS SharedInfo structure

CPKIFBufferPtr GetEncodedSPKIFromKM

(

const CPKIFKeyMaterial &

km

)

Interface: External

Returns an encoded SubjectPublicKeyInfo structure from a Key Material object if possible.

Returns:

CPKIFBuffer object

Definition at line 267 of file PKIFCryptoPPUtils.cpp.

CPKIFBufferPtr GetTBSCertSequence

(

const CPKIFCertificate &

cert

)

Interface: External

Pulls the der-encoded tbsCertificate out of a certificate object for easy signature verification

Returns:

Buffer containing der-encoded tbsCertificate sequence

Parameters:

cert	[in] PKIF certificate object from which the encoded sequence will be taken

CPKIFCredentialPtr MakeCredentialFromP8File	(	const std::string &	file,
		const std::string &	certFile
	)

Interface: External

Creates a Crypto++ Credential given a file. Handle with care, the file and the credential will contain plaintext key material. This will throw if it can't read the file and return an empty credential if the file is readable but invalid.

Returns:

PKIFCryptoPPCredential object

Exceptions:

CPKIFException(COMMON_INVALID_INPUT)

Returns:

PKIFCryptoPPCredential object

Exceptions:

Parameters:

file	[in] string containg the location of the PKCS 8 file
