Detailed Description

Class that implements RC5 encryption.

• Block size is 32 bit (so 16 bit words).
• Only has decrypt method implemented, but encrypt would be possible too.

Member Function Documentation

decrypt()

bool RC5::decrypt	(	uint16_t *	inBuf,
		uint16_t	inBufSize,
		uint16_t *	outBuf,
		uint16_t	outBufSize
	)

Decrypt data with RC5.

Parameters

[in]	inBuf	Input buffer with the encrypted data.
[in]	inBufSize	Size of the input buffer in bytes.
[out]	outBuf	Output buffer to decrypt to.
[in]	outBufSize	Size of the output buffer in bytes.

getInstance()

static RC5 & RC5::getInstance ( )

inlinestatic

Use static variant of singleton, no dynamic memory allocation.

init()

void RC5::init

(
