Detailed Description

DES encryption and decryption class.

Only 56-bit DES is supported, 64-bit key and data size. By contemporary standards, pure DES is insecure, and should not be used in new code.

static MByteString MDes::StaticDecrypt	(	const MByteString &	key,
		const MByteString &	cipherText
	)

static

Static method for encrypting the 64-bit byte string.

Parameters

key	Shall be exactly 8 bytes, binary. Only 56 bits out of 64 are used, the lower bit of every byte is ignored. Notice, the difference from all other MeteringSDK classes is that Key of MDes is binary, not a hex string.
cipherText	Raw bytes of size, exactly 8 bytes.

Returns: MByteString - result plain text, 8 bytes.

static void MDes::StaticDecryptBuffer	(	const char *	key,
		const char *	cipherText,
		char *	plainText,
		unsigned	size = `8`
	)

static

Static method for decrypting the 64-bit byte buffer.

ECB mode is inherently insecure, just as DES with 56-bit key

Parameters

key	Shall be exactly 8 bytes, binary. Only 56 bits out of 64 are used, the lower bit of every byte is ignored. Notice, the difference from all other MeteringSDK classes is that Key of MDes is binary, not a hex string.
cipherText	Raw bytes of size, divisible by 8 bytes.
plainText	Raw bytes of size, divisible by 8 bytes.
size	Size if plain and cipher texts in bytes, divisible by 8 bytes.

static MByteString MDes::StaticEncrypt	(	const MByteString &	key,
		const MByteString &	plainText

static

Static method for encrypting the 64-bit byte string.

Parameters

plainText	Raw bytes of size, exactly 8 bytes.

Returns: MByteString - result cipher text, 8 bytes.
