or

[root@ftp openssl]# rpm -Uvh ./openssl-0.9.6b-32.7asp.i686.rpm
warning: ./openssl-0.9.6b-32.7asp.i686.rpm: V3 DSA signature: NOKEY, key ID 9b8c94f5
error: Failed dependencies:
openssl = 0.9.6b-29 is needed by (installed) openssl-devel-0.9.6b-29

2 things are wrong:

the command is rpm - Uvh openssl-0.9.6b-32.7asp.i686.rpm
libssl.so.2 and libsypto.so.2 is needed

Get libssl.so.2 and libcrypto.so.2 first and then install openssl.
