Class XPRC2Crypto

java.lang.Object
  com.plumtree.openfoundation.security.XPRC2Crypto

All Implemented Interfaces:

IXPCrypto

public class XPRC2Crypto
extends java.lang.Object
implements IXPCrypto

XPRC2Crypto encrypts text using RC2-40 with a maximum password length of 128 characters, and decrypts text encrypted with this method or with an older Plumtree legacy cipher. This class is compatible with PTCipherUtility. Does not currently support generation or use of byte[] keys.

Field Summary

static char

RC2_ENCRYPTION_MARKER_40 40-bit RC2 encryption marker.

Constructor Summary

XPRC2Crypto()
Creates a new XPCrypto object.

Method Summary

boolean	CanDecrypt(java.lang.String toDecrypt) True if recognized as a possible ciphertext compatible with this cryptographic engine.
java.lang.String	Decrypt(java.lang.String toDecrypt, byte[] key) Not implemented in this version, use the Encrypt/Decrypt methods taking a String key.
java.lang.String	Decrypt(java.lang.String strToDecrypt, java.lang.String strKey) Decrypts the string with the key.
java.lang.String	Encrypt(java.lang.String toEncrypt, byte[] key) Not implemented in this version, use the Encrypt/Decrypt methods taking a String key.
java.lang.String	Encrypt(java.lang.String strToEncrypt, java.lang.String strKey) Encrypts a string, based on the key.
byte[]	GenerateKey() Not implemented in this version, use the Encrypt/Decrypt methods taking a String key.
static void	main(java.lang.String[] args) Tests basic encryption and decryption functionality.

Method Detail

Encrypt

public java.lang.String Encrypt(java.lang.String strToEncrypt,
                                java.lang.String strKey)

Encrypts a string, based on the key.

Specified by:

Encrypt in interface IXPCrypto

Parameters:

strToEncrypt - the string to be encrypted

strKey - the encryption key

Returns:

the encrypted string

Decrypt

public java.lang.String Decrypt(java.lang.String strToDecrypt,
                                java.lang.String strKey)

Decrypts the string with the key.

Specified by:

Decrypt in interface IXPCrypto

Parameters:

strToDecrypt - string to be decrypted

strKey - key, need to match the encryption key

Returns:

the decrypted string

main

public static void main(java.lang.String[] args)

Tests basic encryption and decryption functionality.

Parameters:

args - input arguments passed to main method.

CanDecrypt

public boolean CanDecrypt(java.lang.String toDecrypt)

True if recognized as a possible ciphertext compatible with this cryptographic engine. True when the ciphertext argument begins with a marker character indicating Plumtree RC2-40bit encryption or a hex digit 0-9A-F for Plumtree's legacy cipher.

Specified by:

CanDecrypt in interface IXPCrypto

Parameters:

toDecrypt - an encrypted string

Returns:

true if this provider can decrypt the string

Decrypt

public java.lang.String Decrypt(java.lang.String toDecrypt,
                                byte[] key)

Not implemented in this version, use the Encrypt/Decrypt methods taking a String key.

Specified by:

Decrypt in interface IXPCrypto

Parameters:

toDecrypt - the data to decrypt

key - the key to use to decrypt the data

Returns:

the decrypted data

Encrypt

public java.lang.String Encrypt(java.lang.String toEncrypt,
                                byte[] key)

Not implemented in this version, use the Encrypt/Decrypt methods taking a String key.

Specified by:

Encrypt in interface IXPCrypto

Parameters:

toEncrypt - the data to encrypt

key - the key to use to encrypt the data

Returns:

the encrypted data

GenerateKey

public byte[] GenerateKey()
