Detailed Description

An AES symmetric key.

AESSymmetricKey represents a 16, 24 or 32 bytes long AES key to use with an instance AESCipher.

You can create an AESSymmetricKey from random values, using createRandom() or from specific data, using createFromData(). You can also generate an AESSymmetricKey from a passphrase, using createFromPassphrase().

Constructor & Destructor Documentation

AESSymmetricKey() [1/2]

logicalaccess::openssl::AESSymmetricKey::AESSymmetricKey ( size_t  size )

explicitprotected

Create a new random AESSymmetricKey.

Parameters

size	The size of the key. Must be 16, 24 or 32.

AESSymmetricKey() [2/2]

logicalaccess::openssl::AESSymmetricKey::AESSymmetricKey ( const ByteVector &  data )

explicitprotected

Create an AESInitializationVector from existing data.

Parameters

data

The data.

Warning

If data is not 16, 24 or 32 bytes long, the behavior is undefined.

Member Function Documentation

createFromData()

AESSymmetricKey logicalaccess::openssl::AESSymmetricKey::createFromData ( const ByteVector &  data )

static

Create a symmetric key from the specified data.

Parameters

data

The data.

Returns

The symmetric key.

Warning

If data is not 16, 24 or 32 bytes long, the behavior is undefined.

createFromPassphrase()

AESSymmetricKey logicalaccess::openssl::AESSymmetricKey::createFromPassphrase ( const std::string &  passphrase )

static

Create a 32 bytes long symmetric key from the specified passphrase.

Parameters

passphrase

The passphrase.

Returns

The symmetric key.

createRandom()

AESSymmetricKey logicalaccess::openssl::AESSymmetricKey::createRandom ( size_t  size )

static

Create a random symmetric key of a given size.

Parameters

size	The size of the key. Must be 16, 24 or 32.

Returns

The symmetric key.
