Class checksum

Method Summary
	`__init__(self, block_name, request, algorithm, length, endian, name)` Create a checksum block bound to the block with the specified name.
Raw	`checksum(self, data)` Calculate and return the checksum (in raw bytes) over the supplied data.
	`render(self)` Calculate the checksum of the specified block using the specified algorithm.

Class Variable Summary
`dict`	`checksum_lengths` = `{'crc32': 4, 'sha1': 20, 'adler32': 4...`

Method Details

Create a checksum block bound to the block with the specified name. You *can not* create a checksm for any currently open blocks.

Parameters:: block_name - Name of block to apply sizer to
(type=String); request - Request this block belongs to
(type=s_request); algorithm - (Optional, def=crc32) Checksum algorithm to use. (crc32, adler32, md5, sha1)
(type=String); length - (Optional, def=0) Length of checksum, specify 0 to auto-calculate
(type=Integer); endian - (Optional, def=LITTLE_ENDIAN) Endianess of the bit field (LITTLE_ENDIAN: <, BIG_ENDIAN: >)
(type=Character); name - Name of this checksum field
(type=String)

Calculate and return the checksum (in raw bytes) over the supplied data.

Parameters:: data - Rendered block data to calculate checksum over.
(type=Raw)

Calculate the checksum of the specified block using the specified algorithm.
