void QucikAES::setKeySize(unsigned int size)

Changes key size.

void QuickAES::encryptData(unsigned char *data, unsigned char *key)

Encrypts 128 bit data with AES.

void QuickAES::decryptData(unsigned char *data, unsigned char *key)

Decrypts 128 bit data with AES.

void QuickAES::encryptECB(unsigned char *data, unsigned char *key, unsigned char *result, unsigned int size)

Encrpyts data with ECB block cipher mode of operation.

void QuickAES::encryptECB(unsigned char *data, unsigned char *key, unsigned char *result, unsigned int size)

Decrpyts data with ECB block cipher mode of operation.

void QucikAES::encryptCBC(unsigned char *data, unsigned char *key, unsigned char *result, unsigned int size, unsigned char *iv)

Encrypts data with CBC block cipher mode of operation.

void QucikAES::decryptCBC(unsigned char *data, unsigned char key, unsigned char *result, unsigned int size, unsigned char *iv)

Decrypts data with CBC block cipher mode of operation.

void QucikAES::cryptOFB(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*iv)

Encrypts and decrypts data with OFB block cipher mode of operation.

void QucikAES::cryptCTR(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*ic)

Encrypts and decrypts data with CTR block cipher mode of operation.

void QucikAES::encryptCFB(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*iv)

Encrypts data with 128 bit CFB block cipher mode of operation.

void QucikAES::decryptCFB(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*iv)

Decrypts data with 128 bit CFB block cipher mode of operation.

void QucikAES::encryptCFB8(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*iv)

Encrypts data with 8 bit CFB block cipher mode of operation.

void QucikAES::decryptCFB8(unsigned char \*data, unsigned char \*key, unsigned char \*result, unsigned int size, unsigned char \*iv)

Decrypts data with 128 bit CFB8 block cipher mode of operation.
