| ADLER32 |
The ADLER32 algorithm is a checksum specified in RFC 1950 "ZLIB
Compressed Data Format". The 32-bit output is encoded in hexadecimal
(using between 1 and 8 ASCII characters from 0-9, A-F, and a-f;
leading 0's are allowed). For example, ADLER32=03da0195 and ADLER32=3DA0195
are both valid checksums for the 4-byte message "Wiki". |

| CRC32c |
The CRC32c algorithm is a 32-bit cyclic redundancy check. It
achieves a better hamming distance (for better error-detection performance)
than many other 32-bit CRC functions. Other places it is used include iSCSI
and SCTP. The 32-bit output is encoded in hexadecimal (using between 1 and
8 ASCII characters from 0-9, A-F, and a-f; leading 0's are allowed). For
example, CRC32c=0a72a4df and crc32c=A72A4DF are both valid checksums for
the 3-byte message "dog". |

command, as defined by the Single UNIX
Specification, Version 2 The Open Group. The Single UNIX Specification,
Version 2 - 6 Vol Set for UNIX 98. Document number T912,
