Fixed In Version: libgcrypt-1.4.5-5.el6_1.1
Doc Type: Enhancement
Doc Text:
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.
