Chapter 17. Extension Joiner
the base-64 encoded blob using the dumpasn1 utility. For information on the AtoB utility, see
Chapter 7, ASCII to
extras/4/i386/repodata/repoview/dumpasn1-0-20050404-1.fc4.html.
a. Run the AtoB utility to convert the ASCII to binary.
AtoBinput_file output_file
where input_file is the path and file containing the base-64 encoded data in ASCII and
output_file is the path and file for the utility to write the binary output.
b. Run the dumpasn1 utility.
dumpasn1output_file
where output_file is the path and file containing the binary data. The output looks similar to
this:
0 30 76: SEQUENCE {
2 30 46: SEQUENCE {
4 06 3: OBJECT IDENTIFIER extKeyUsage (2 5 29 37)
9 01 1: BOOLEAN TRUE

: 02 55 53
: }
: }
0 warnings, 0 errors.
If the output data do not appeat to be correct, check that the original Java™ extension files are
correct, and repeat converting the files from ASCII to binary and dumping the data until the correct
output is returned.
5. When the extensions have been verified, copy the base-64 encoded blob that was created by
running ExtJoiner to the Certificate System wizard screen, and generate the certificate or the
certificate signing request (CSR).
