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.

NAME

       rdd-verify - verifies checksums and hash values generated by rdd-copy(1)

SYNOPSIS

       rdd-verify [OPTION] file1 ...

DESCRIPTION

       Rdd-verify  verifies  checksums	and  hash values generated by rdd-copy(1).  Rdd stores checksums (Adler32 or CRC32) in files.  These files
       must be passed to rdd-verify for verification.

       Hash values (MD5 or SHA1) computed by rdd-copy(1) must be passed to rdd-verify on the command line as hexadecimal strings.

       Rdd-verify reads all input files (file1, ...) and recomputes the checksums and hash values that the user wishes to verify.   The  verifica-
       tion will very likely fail if the concatenation of the input files is different from the source that was copied by rdd-copy(1).

OUTPUT

       All verification errors are reported on stderr.

OPTIONS

       -?, --help
	      Print a usage message.

       -V, --version
	      Report version number and exit.

       -v, --verbose
	      Be verbose (more messages).

       -v, --verbose
	      Be verbose (more messages).

       --checksum, --adler32 file
	      Verify the Adler32 checksums stored in file.

       --crc, --crc32 file
	      Verify the CRC32 checksums stored in file.

       --md5, --md5 digest
	      Recompute the MD5 hash value.  It should be equal to digest.

       --sha, --sha1 digest
	      Recompute the SHA1 hash value.  It should be equal to digest.

       A digest argument is a hexadecimal string.  Leading zeroes may not be omitted.

EXAMPLES

       rdd-verify --md5 0123456789abcdef0123456789abcdef disk.img

	      Compute the MD5 hash value over disk.img and verify whether it equals 0123456789abcdef0123456789abcdef.

       rdd-verify --adler32 checksums.a32 disk.img

	      Compute the adler32 checksums over disk.img and compare each checksum to the corresponding checksum in checksums.a32.
