Find applications that use openssl

I have a OpenSSL configured in my RHEL machine.
I need to find the list of applications that use or depend on OpenSSL.
Is it possible to know which application is using the shared library?

Code:

ldd `which openssl`
 linux-gate.so.1 =>  (0x00b3a000)
        libssl.so.10 => /usr/lib/libssl.so.10 (0x0059a000)
        libgssapi_krb5.so.2 => /lib/libgssapi_krb5.so.2 (0x0040a000)
        libkrb5.so.3 => /lib/libkrb5.so.3 (0x00dbf000)
        libcom_err.so.2 => /lib/libcom_err.so.2 (0x002f9000)
        libk5crypto.so.3 => /lib/libk5crypto.so.3 (0x00a2a000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x009cf000)
        libcrypto.so.10 => /usr/lib/libcrypto.so.10 (0x00601000)
        libdl.so.2 => /lib/libdl.so.2 (0x0038e000)
        libz.so.1 => /lib/libz.so.1 (0x00bbf000)
        libc.so.6 => /lib/libc.so.6 (0x007c7000)
        libkrb5support.so.0 => /lib/libkrb5support.so.0 (0x00587000)
        libkeyutils.so.1 => /lib/libkeyutils.so.1 (0x0016f000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00173000)
        /lib/ld-linux.so.2 (0x0021e000)
        libselinux.so.1 => /lib/libselinux.so.1 (0x0018e000)

Will this work,because i am not sure about this

Code:

rpm -ql <app> | grep <shared library>
