Function Documentation

void fairport::disk::cyclic	(	void *	pdata,
		ulong	cb,
		ulong	key
	)		[inline]

Modifies the data block in place, according to the cyclic method.

This algorithm is called to "encrypt" external data if the crypt_method of the file is set to crypt_method_cyclic

Parameters:

[in,out]	pdata	A pointer to the data to "encrypt". This data is modified in place
[in]	cb	The size of the block of data
[in]	key	The key used in the cycle process. Typically this is the block_id of the data being "encrypted".

void fairport::disk::permute	(	void *	pdata,
		ulong	cb,
		bool	encrypt
	)		[inline]

Modifies the data block in place, according to the permute method.

This algorithm is called to "encrypt" external data if the crypt_method of the file is set to crypt_method_permute

Parameters:

[in,out]	pdata	A pointer to the data to "encrypt". This data is modified in place
[in]	cb	The size of the block of data
[in]	encrypt	True if "encrypting", false is unencrypting
