libcrypto.so is a shared library - not a Java jar. From the OpenSSl documentation:

OVERVIEW

libcrypto consists of a number of sub-libraries that implement the individual algorithms.

The functionality includes symmetric encryption, public key cryptography and key agreement, certificate handling, cryptographic hash functions and a cryptographic pseudo-random number generator.

SYMMETRIC CIPHERS

blowfish(3), cast(3), des(3), idea(3), rc2(3), rc4(3), rc5(3)

PUBLIC KEY CRYPTOGRAPHY AND KEY AGREEMENT

dsa(3), dh(3), rsa(3)

CERTIFICATES

x509(3), x509v3(3)

AUTHENTICATION CODES, HASH FUNCTIONS

hmac(3), md2(3), md4(3), md5(3), mdc2(3), ripemd(3), sha(3)

AUXILIARY FUNCTIONS

err(3), threads(3), rand(3), OPENSSL_VERSION_NUMBER(3)

INPUT/OUTPUT, DATA ENCODING

asn1(3), bio(3), evp(3), pem(3), pkcs7(3), pkcs12(3)

INTERNAL FUNCTIONS

bn(3), buffer(3), lhash(3), objects(3), stack(3), txt_db(3)

There are lots of tools you can use to "see" what is in the library. The most useful to start with is probably nm.
