4.84. libgcrypt

Updated libgcrypt packages that add one enhancement are now available for Red Hat Enterprise Linux 5.
The libgcrypt library provides general-purpose implementations of various cryptographic algorithms.


With Federal Information Processing Standards (FIPS) mode enabled, the libgcrypt library always started in the soft FIPS mode which allows applications to use the MD5 cryptographic hash algorithm. The libgcrypt API previously did not allow the library to programmatically switch from the soft FIPS mode to the enforced FIPS mode. With this update, if the application does not need MD5 support for the Transport Layer Security (TLS) protocol or non-cryptographic purposes, libgcrypt can be preset in the enforced FIPS mode.
All users of libgcrypt are advised to upgrade to these updated packages, which add this enhancement.
