Member Function Documentation

int PrivDES::decrypt (  const unsigned char *  key, const unsigned int  key_len, const unsigned char *  buffer, const unsigned int  buffer_len, unsigned char *  out_buffer, unsigned int *  out_buffer_len, const unsigned char *  privacy_params, const unsigned int  privacy_params_len, const unsigned long  engine_boots, const unsigned long  engine_time )  [virtual]

Decrypt the buffer with the given key. This method needs the privacy parameters field for the given message. Parameters: key  - pointer to the (fixed length) dencryption key key_len  - length of encryption key buffer  - pointer to the encrypted buffer buffer_len  - length of the buffer out_buffer  - pointer to the buffer for the decryptet data out_buffer_len  - Input: Length of the output buffer. Output: Bytes written privacy_params  - Buffer, where the privacy parameters are read from. privacy_params_len  - Length of the privacy parameters buffer engine_boots  - The engine boots value for the message engine_time  - The engine time value for the message Returns: SNMPv3_USM_OK on success Implements Priv.

int PrivDES::encrypt (  const unsigned char *  key, const unsigned int  key_len, const unsigned char *  buffer, const unsigned int  buffer_len, unsigned char *  out_buffer, unsigned int *  out_buffer_len, unsigned char *  privacy_params, unsigned int *  privacy_params_len, const unsigned long  engine_boots, const unsigned long  engine_time )  [virtual]

Encrypt the buffer with the given key. This method fills the privacy parameters field of the given message. Parameters: key  - pointer to the encryption key key_len  - length of encryption key buffer  - pointer to the unencrypted buffer buffer_len  - length of the buffer out_buffer  - pointer to the buffer for the encryptet data out_buffer_len  - Input: Length of the output buffer. Output: Bytes written privacy_params  - Buffer, where the privacy parameters are written to. privacy_params_len  - Length of the privacy parameters buffer engine_boots  - The engine boots value for the message engine_time  - The engine time value for the message Returns: SNMPv3_USM_OK on success Implements Priv.
