RHEA-2011:0515 - libgcrypt enhancement update

Synopsis

libgcrypt enhancement update

Type/Severity

Product Enhancement Advisory

Topic

An updated libgcrypt package that introduces a feature enhancement is now available for Red Hat Enterprise Linux 6.

Description

The libgcrypt library provides general-purpose implementations of various cryptographic algorithms.

This updated libgcrypt package includes the following enhancement:

  • In FIPS mode, libgcrypt can now use a configurable source of RNG (Random Number Generator) seed. On systems with sufficient amount of entropy gathered from the kernel entropy sources or systems with hardware RNGs, the system administrator can add the "/etc/gcrypt/rngseed" symbolic link pointing to the "/dev/random" device node or a hardware RNG device. This symbolic link will be then opened and read by the libgcrypt library to initialize its RNG. (BZ#703490)

All users of libgcrypt are advised to upgrade to this updated package, which adds this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
