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.
