Verify the download package

MD5 files can be used verify the integrity of packages that are downloaded from IBM. IBM provides MD5 values for all recent eAssemblies and Update Packages.

Before beginning

We need to identify or obtain an MD5 hash utility to generate a hash signature. Most UNIX and Linux operating systems include utilities to generate an MD5 hash. Microsoft Windows does not include an MD5 utility, but many third-party options are available.

Task info

The following steps provide high-level instructions to verify the download package:

Procedure

1. Use your MD5 hash utility to generate a hash signature of your copy of the package.

2. Compare the generated signature hash with the IBM MD5 value. Ensure that the values are identical. To find IBM MD5 values, see

   • eAssemblies

   • WebSphere Commerce Developer fix packs and eAssemblies

   • If the values are identical, then proceed to install the package.

   • If the values are not identical, then the installation package might be corrupted. Try to download the package from the trusted IBM source and verify the values. If the values do not match, then contact IBM Support.
