Detailed Description

AES cipher class.

AESCipher is a symmetric cipher class that relies on OpenSSL's implementation of the AES algorithm. Take a look at SymmetricCipher for usage.

Constructor & Destructor Documentation

◆ AESCipher()

logicalaccess::openssl::AESCipher::AESCipher ( EncMode _mode = ENC_MODE_CBC )

inlineexplicit

Constructor.

Parameters

_mode The encryption mode. Default is CBC.

Member Function Documentation

◆ getBlockSize()

unsigned char logicalaccess::openssl::AESCipher::getBlockSize ( ) const

overridevirtual

Implements logicalaccess::openssl::SymmetricCipher.

◆ getEVPCipher()

const EVP_CIPHER * logicalaccess::openssl::AESCipher::getEVPCipher ( const SymmetricKey & key ) const

overrideprotectedvirtual

Get the OpenSSL EVP cipher.

Parameters

key The key.

Returns: The EVP cipher.

getEVPCipher() returns the OpenSSL EVP cipher that should be used with key. The resulting EVP cipher mainly depends on the size of key.

If no suitable cipher is found, getEVPCipher() returns NULL.

Implements logicalaccess::openssl::OpenSSLSymmetricCipher.
