    Question How to decrypt? (if you know plaintext, ciphertext,...)

    Hi!

    I have a table with 2400 rows and it is encrypted (I don't know how!)

    How to decrypt it?
    if you know plaintext, ciphertext, maybe and password.
    Look:
    Java Code:
    About			->	75505C4047
    Pėr			->	64D941
    Absolute reference	->	7550405A5F424C53144B50565443555A5354
    Rererencė absolute	->	6657555041525655DF195452425E5C414454
    
    
    
    Absolute cell reference: In a formula, the exact address of a cell, regardless of the position of the cell that contains the formula. An absolute cell reference takes the form $A$1.
    
    	
    	-^-

    well that's pretty much dependent on how it was encrypted :P I'm not a code expert, but I think you have to know the encryption method in order to decrypt it. Then the question is more: how do I get to know how something is encrypted? With that question you should try a cryptography forum, not a java forum. You might also try a maths forum.
    good luck,
    Joost

    @OP, this is forum discussing about Java related technologies. Not related with cryptography and stuff. It's better to ask your question in a relevant forum. Adding more, you have to find several things to solve this.

    1. Is encrypted or not
    2. Public algorithm, and the public keys

    Do you know these, or you are trying to do an attack on someones' data?
