Classes
class Cipher
Represents the abstract base class from which all implementations of
symmetric/asymmetric encryption algorithms must inherit. 
class CipherFactory

of private and public key.
class ECKeyImpl
Elliptic Curve key clas implementation.
class EVPCipherImpl
An implementation of the Cipher class for
asymmetric (public-private key) encryption
based on the OpenSSL crypto library.
class EVPPKey
Utility class for conversion of native keys to EVP.
class EncryptingInputStream

of private and public key.
class KeyPairImpl
Class KeyPairImpl
class OpenSSLException
class OpenSSLInitializer
Initalizes the OpenSSL library.
class PKCS12Container
This class implements PKCS#12 container functionality.
class RSACipherImpl
An implementation of the Cipher class for
asymmetric (public-private key) encryption
based on the the RSA algorithm in OpenSSL's
crypto library.
class RSADigestEngine
This class implements a Poco::DigestEngine that can be
used to compute a secure digital signature.
class RSAKey
This class stores an RSA key pair, consisting
of private and public key.
class RSAKeyImpl
class RSAKeyImpl
class X509Certificate
This class represents a X509 Certificate.
Functions
getError 
inline std::string & getError(
std::string & msg
);
Appends OpenSSL error(s) to msg and returns the augmented error description.
initializeCrypto
void initializeCrypto();
Initialize the Crypto library, as well as the underlying OpenSSL libraries, by calling OpenSSLInitializer::initialize().
Should be called before using any class from the Crypto library. The Crypto library will be initialized automatically, through OpenSSLInitializer instances held by various Crypto classes (Cipher, CipherKey, RSAKey, X509Certificate). However, it is recommended to call initializeCrypto() in any case at application startup.
Can be called multiple times; however, for every call to initializeCrypto(), a matching call to uninitializeCrypto() must be performed.
uninitializeCrypto
void uninitializeCrypto();
Uninitializes the Crypto library by calling OpenSSLInitializer::uninitialize().
