File Information

Library: Crypto
Package: Cipher
Header: Poco/Crypto/CipherFactory.h

Description

A factory for Cipher objects. See the Cipher class for examples on how to use the CipherFactory.

Member Summary

Member Functions: createCipher, defaultFactory

Constructors

CipherFactory

CipherFactory();

Creates a new CipherFactory object.

Destructor

~CipherFactory virtual

virtual ~CipherFactory();

Destroys the CipherFactory.

Member Functions

createCipher

Cipher * createCipher(
    const CipherKey & key
);

Creates a Cipher object for the given Cipher name. Valid cipher names depend on the OpenSSL version the library is linked with; see the output of 

openssl enc --help

for a list of supported block and stream ciphers.

Common examples are:

  • AES: "aes-128", "aes-256"
  • DES: "des", "des3"
  • Blowfish: "bf"

createCipher

Cipher * createCipher(
    const RSAKey & key,
    RSAPaddingMode paddingMode = RSA_PADDING_PKCS1
);

Creates a RSACipher using the given RSA key and padding mode for public key encryption/private key decryption.

createCipher

Cipher * createCipher(
    const EVPPKey & key
);

Creates an EVPCipher using the given EVP key for public key encryption/private key decryption.

defaultFactory static

static CipherFactory & defaultFactory();

Returns the default CipherFactory.
