◆ decryptStringGpg()

static std::basic_string<unsigned char> rosbag::decryptStringGpg	(	std::string const &	user,
		std::string const &	input
	)

static

Decrypt string using GPGME.

Returns: Decrypted string

Parameters

user	User name of the GPG key to be used for decryption
input	Encrypted string

This method decrypts the given encrypted string. This method throws BagException in case of errors.

Definition at line 118 of file aes_encryptor.cpp.

◆ encryptStringGpg()

static std::string rosbag::encryptStringGpg	(	std::string &	user,
		std::basic_string< unsigned char > const &	input
	)

static

Encrypt string using GPGME.

Returns: Encrypted string

Parameters

user	User name of the GPG key to be used for encryption
input	Input string to be encrypted

This method encrypts the given string using the GPG key owned by the specified user. This method throws BagException in case of errors.

Definition at line 60 of file aes_encryptor.cpp.

◆ getGpgKey()

void rosbag::getGpgKey	(	gpgme_ctx_t &	ctx,
