Member Function Documentation

decryptData()

virtual void tenduke::crypto::Cipher::decryptData ( const ::tenduke::utl::DataSpan & ciphertext, ::tenduke::utl::DataSink & plaintext ) const

pure virtual

Utility method to decrypt data.

This method decrypts the provided data, encrypted by ::encryptData() method.

Parameters

ciphertext	the encrypted data
plaintext	the decrypted data

Implemented in LibcryptoAESCipher, tenduke::crypto::aes::libcrypto::LibcryptoAESCipher, and tenduke::crypto::win::cng::WinCNGAESCipher.

encryptData()

virtual void tenduke::crypto::Cipher::encryptData ( const ::tenduke::utl::DataSpan & plaintext, ::tenduke::utl::DataSink & ciphertext ) const

pure virtual

Utility method to encrypt data.

This method encrypts the provided data and outputs a binary data object which contains:

• nonce / IV (if used by the cipher), automatically generated
• the ciphertext
• the authentication tag (if used by the cipher)

Parameters

plaintext	the data to encrypt
ciphertext	the encrypted data

Implemented in AESGCMCipher, LibcryptoAESCipher, tenduke::crypto::aes::AESGCMCipher, tenduke::crypto::aes::libcrypto::LibcryptoAESCipher, and tenduke::crypto::win::cng::WinCNGAESCipher.
