Function Documentation

lws_gencrypto_bits_to_bytes()

LWS_VISIBLE LWS_EXTERN int lws_gencrypto_bits_to_bytes

(

int

bits

)

lws_gencrypto_bits_to_bytes() - returns rounded up bytes needed for bits

Parameters

bits	Returns the number of bytes needed to store the given number of bits. If a byte is partially used, the byte count is rounded up.

lws_base64_size()

LWS_VISIBLE LWS_EXTERN int lws_base64_size

(

int

bytes

)

lws_base64_size() - returns estimated size of base64 encoding

Parameters

bytes

Returns a slightly oversize estimate of the size of a base64 encoded version of the given amount of unencoded data.

lws_gencrypto_padded_length()

LWS_VISIBLE LWS_EXTERN size_t lws_gencrypto_padded_length	(	size_t	block_size,
		size_t	len
	)

lws_gencrypto_padded_length() - returns PKCS#5/#7 padded length

Parameters

blocksize	- blocksize to pad to
len	- Length of input to pad

Returns the length of a buffer originally of size len after PKCS#5 or PKCS#7 padding has been applied to it.
