Member Function Documentation

RSA * digidoc::RSACrypt::loadRSAPrivateKey ( const std::string & path ) throw (IOException)

static

Loads RSA private key from file. NB! This struct must be freed using RSA_free() function from OpenSSL or with RSA_scope struct.

Parameters

path	PEM formatted RSA private key file path.

Returns: returns RSA private key parsed from file.

Exceptions

IOException throws exception if the file does not contain RSA private key.

Here is the caller graph for this function:

std::vector< unsigned char > digidoc::RSACrypt::sign ( const Signer::Digest & digest ) throw (IOException)

Signs the digest with provided RSA private key.

Parameters

digestMethod	digest method (e.g NID_sha1 for SHA1, see openssl/obj_mac.h).
digest	digest value, this value is signed with the private RSA key.

Returns: returns signature.

Exceptions

IOException

Definition at line 75 of file RSACrypt.cpp.

References THROW_IOEXCEPTION.

Referenced by digidoc::RSASigner::sign().

Here is the caller graph for this function:

bool digidoc::RSACrypt::verify	(	int	digestMethod,
		std::vector< unsigned char >	digest,
		std::vector< unsigned char >	signature
	)		throw (IOException)

Verify signature with RSA public key from X.509 certificate.

Parameters

digestMethod	digest method (e.g NID_sha1 for SHA1, see openssl/obj_mac.h).
digest	digest value, this value is compared with the digest value decrypted from the `signature`.
signature	signature value, this value is decrypted to get the digest and compared with the digest value provided in `digest`.

Returns: returns true if the signature value matches with the digest, otherwise false is returned.

Exceptions

IOException throws exception if X.509 certificate is not missing or does not have a RSA public key.
