Обсуждение: libssl.so.0, libcrypto.so.0 needed when installing RPM 7.1.2 on RH 6.2?

I downloaded postgresql RPM 7.1.2 from postgresql.org, binary version built
for Redhat 6.2.
When installing the package rpm reports a dependency error, not finding
libssl.so.0 & libcrypto.so.0.

where can i find these two libraries? None of packages in RH 6.2 CD contains
that.

thank you.
