Member Function Documentation

◆ addFieldsToFileHeader()

void rosbag::NoEncryptor::addFieldsToFileHeader ( ros::M_string & header_fields ) const

inlinevirtual

Add encryptor information to bag file header.

Parameters

header_fields The header fields of the bag

Called for a bag being written, this method adds encryptor-specific fields to the bag file header. Those fields are used when decrypting the bag. ENCRYPTOR_FIELD_NAME must be specified in the header except for NoEncryptor.

Implements rosbag::EncryptorBase.

Definition at line 52 of file no_encryptor.h.

◆ decryptChunk()

void rosbag::NoEncryptor::decryptChunk	(	ChunkHeader const &	chunk_header,
		Buffer &	decrypted_chunk,
		ChunkedFile &	file
	)		const

virtual

Decrypt chunk.

Parameters

chunk_header	The header of the encrypted chunk
decrypted_chunk	The buffer where decrypted chunk is written to
file	The bag file stream from which the encrypted chunk is read

This method reads the encrypted chunk from file stream, decrypts, and writes it to decrypted_chunk.

Implements rosbag::EncryptorBase.

Definition at line 47 of file no_encryptor.cpp.

◆ encryptChunk()

uint32_t rosbag::NoEncryptor::encryptChunk	(	const uint32_t	chunk_size,
		const uint64_t	chunk_data_pos,
		ChunkedFile &	file
	)

virtual

Encrypt chunk.

Returns: The byte size of the encrypted chunk

Parameters

chunk_size	The byte size of the original chunk
chunk_data_pos	The start position of the chunk data in bag file stream
file	The bag file stream

This method reads the original chunk from [chunk_data_pos, chunk_data_pos+chunk_size), encrypts it, and writes back to the file stream starting at chunk_data_pos.

Implements rosbag::EncryptorBase.

Definition at line 45 of file no_encryptor.cpp.

◆ initialize()

void rosbag::NoEncryptor::initialize	(	Bag const &	bag,
		std::string const &	plugin_param
	)

inlinevirtual

Initialize encryptor.

Parameters

bag	The Bag instance
plugin_param	The string parameter used while initializing the encryptor

This method is called by setEncryptorPlugin, which loads an encryptor plugin.

Implements rosbag::EncryptorBase.

Definition at line 49 of file no_encryptor.h.

◆ readEncryptedHeader()

bool rosbag::NoEncryptor::readEncryptedHeader	(	boost::function< bool(ros::Header &)>	read_header,
		ros::Header &	header,
		Buffer &	header_buffer,
		ChunkedFile &	file
	)

virtual

Read encrypted header from bag file.

Parameters

read_header	The functor reading unencrypted header
header	The header object read
header_buffer	The header buffer read
file	The bag file stream

This method reads and decrypts encrypted header to output header object (header) and buffer (header_buffer).

Implements rosbag::EncryptorBase.

Definition at line 56 of file no_encryptor.cpp.

◆ readFieldsFromFileHeader()

void rosbag::NoEncryptor::readFieldsFromFileHeader ( ros::M_string const & header_fields )

inlinevirtual

Read encryptor information from bag file header.

Parameters

header_fields The header fields of the bag

Called for a bag being read, this method reads encryptor-specific fields from the bag file header.

Implements rosbag::EncryptorBase.

Definition at line 53 of file no_encryptor.h.

◆ writeEncryptedHeader()

void rosbag::NoEncryptor::writeEncryptedHeader	(	boost::function< void(ros::M_string const &)>	write_header,
		ros::M_string const &	header_fields,
		ChunkedFile &	file
	)

virtual

Write encrypted header to bag file.

Parameters

write_header	The functor writing unencrypted header
header_fields	The header fields to be written
file	The bag file stream

This method encrypts given header fields, and writes them to the bag file.

Implements rosbag::EncryptorBase.
