Hi Ricky,
Please have a look at following tutorial link
http://etutorials.org/Programming/secure+programming/Chapter+10.+Public+Key+Infrastructure/10.5+Performing+X.509+Certificate+Verification+with+OpenSSL/
Above link could be of your help.

The code in demos/maurice reads a certificate and extracts an EVP_PKEY from it,
which is
Traditionally, you handle this by encrypting a fixed length symetric key
using RSA (i.e. an AES key) and use that key to encrypt any serious amounts
of data.

Hi, everyone.
In the process of moving to a new compiler, we learned that OpenSSL 1.0.1
crypto\asn1\tasn_prn1.c has one use of "bool" as a function argument (in
asn1_print_boolean_ctx()) and one as a local variable (in
asn1_primitive_print()). Since bool is now seen as a defined type, the
com
In addition, I find that EVP_DigestInit_ex ends up bumping the reference count
*twice*...
In eng_table.c:
/* Try to initialise the ENGINE? */
if((ret->funct_ref > 0) || !(table_flags & ENGINE_TABLE_FLAG_NOINIT))
initres = engine_unlocked_init(ret);
else
BTW, this is with OpenSSL 1.0.1; I did not try an older version.

Where is any working example to encrypt file or long string using
RSA Public or private key.
