Encryption
Encrypt given data. If from is non-zero, first from bytes of input will NOT be encrypted, i.e. data between input.begin() and input.begin()+from will be copied to output straightly, and data between input.begin()+from and input.end() will be encrypted and append to output. Parameters [in] input Data to be encrypted [out] output A buffer to receive the result [in] from Index in input from where data will be encrypted Returns 0: Succeeded -1: Invalid parameter
int	encrypt (const std::vector< char > &input, std::vector< char > &output, size_t from=0) const
int	encrypt (const std::vector< signed char > &input, std::vector< signed char > &output, size_t from=0) const
int	encrypt (const std::vector< unsigned char > &input, std::vector< unsigned char > &output, size_t from=0) const
int	encrypt (const std::string &input, std::string &output, size_t from=0) const
Decryption
Decrypt given data. If from is non-zero, first from bytes of input will NOT be decrypted, i.e. data between input.begin() and input.begin()+from will be copied to output straightly, and data between input.begin()+from and input.end() will be decrypted and append to output. Parameters [in] input Data to be decrypted [out] output A buffer to receive the result [in] from Index in input from where data will be decrypted Returns 0: Succeeded -1: Invalid parameter -2: Input data format error

Detailed Description

A convenient interface for Advanced Encryption Standard (AES) algorithm.

Note

CEncryptorAes object can NOT be copied.

Constructor & Destructor Documentation

CEncryptorAes::CEncryptorAes ( )

inline

Construct a default object.

Key size defaults to L128.
You need setKey or setKeyAndIntensity before encryption/decryption operations.

CEncryptorAes::CEncryptorAes ( const std::string &  key, EKeyIntensity  intensity  )

inline

Construct an object.

Parameters

key	Encryption key (password)
intensity	Key size

Member Function Documentation

void CEncryptorAes::setIntensity ( EKeyIntensity  intensity )

inline

Set key size.

Parameters

intensity

Key size

void CEncryptorAes::setKey ( const std::string &  key )

inline

Set encryption key (password).

Password is an arbitrary string.

Parameters

key	Encryption key (password)

void CEncryptorAes::setKeyAndIntensity ( const std::string &  key, EKeyIntensity  intensity  )

inline

Set encryption key (password) and key size.

Password is an arbitrary string.

Parameters

key	Encryption key (password)
intensity	Key size
