One way to verify is to compare the file sizes of the two files.
An 'ls -l' command would tell you lots about each file, including size.

What have you tried, and what have you written so far for your process?

NAME
cr_verify - verify integrity of crash dump SYNOPSIS
DESCRIPTION
uncompresses and verifies the sizes and checksums of every file in the crash dump identified by crash_cb. flags is a bitmask of zero or more of the following flag values: will not attempt to verify checksums of files in the crash dump if this flag is set. Only sizes will be verified. will write messages to stderr during time-consuming operations (decompressions and checksums) if this flag is set. will write messages to stderr describing any validation problems that are encountered. If this flag is set, should not be called when returns; repeated error messages would result. RETURN VALUE
Returns zero for success. Other possible return values are described in libcrash(5). EXAMPLES
The following call to cr_verify(3) verifies the integrity of the dump. WARNINGS
Because it uncompresses and checksums all files in a dump, can be very time-consuming. If was not specified, the calling application should notify its user before calling that there may be a significant delay. AUTHOR
was developed by HP. SEE ALSO
cr_open(3), cr_perror(3), libcrash(5). cr_verify(3)
