Member Function Documentation

decryptData()

void tenduke::crypto::win::cng::WinCNGAESCipher::decryptData ( const ::tenduke::utl::DataSpan & ciphertext, ::tenduke::utl::DataSink & plaintext ) const

overridevirtual

Utility method to decrypt data.

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

Parameters

ciphertext	the encrypted data
plaintext	the decrypted data

Implements tenduke::crypto::Cipher.

encryptData() [1/2]

void tenduke::crypto::win::cng::WinCNGAESCipher::encryptData ( const ::tenduke::utl::DataSpan & nonce, const ::tenduke::utl::DataSpan & plaintext, ::tenduke::utl::DataSink & ciphertext ) const

overridevirtual

Encrypts data using the provided nonce.

Writes [nonce][ciphertext][authentication tag] to ciphertext.

Parameters

nonce	the nonce (IV) to use; must be GCM_NONCE_SIZE bytes
plaintext	data to encrypt
ciphertext	sink that receives the output

Implements tenduke::crypto::aes::AESGCMCipher.

encryptData() [2/2]

void tenduke::crypto::win::cng::WinCNGAESCipher::encryptData ( const ::tenduke::utl::DataSpan & plaintext, ::tenduke::utl::DataSink & ciphertext ) const

overridevirtual

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

Reimplemented from tenduke::crypto::aes::AESGCMCipher.
