java.lang.Objectorg.gregoire.util.crypto.BlowfishEasy
support class for easy string encryption with the Blowfish algorithm, now in CBC mode with a SHA-1 key setup and correct padding - the purposes of this module is mainly to show a possible implementation with Blowfish ...
Constructor Summary | |
BlowfishEasy(java.lang.String sPassword)
constructor to set up a string as the key (oversized password will be cut) |
Method Summary | |
java.lang.String |
decryptString(java.lang.String sCipherText)
decrypts a hexbin string (handling is case sensitive) |
void |
destroy()
destroys (clears) the encryption engine, after that the instance is not valid anymore |
java.lang.String |
encryptString(java.lang.String sPlainText)
encrypts a string (treated in UNICODE) using the standard Java random generator, which isn't that great for creating IVs |
java.lang.String |
encryptString(java.lang.String sPlainText,
java.util.Random rndGen)
encrypts a string (treated in UNICODE) |
Methods inherited from class java.lang.Object |
