    Default security(encrypt/decrypt) across machines

    hi ,
    i am using AES/CBC/PKCS5Padding algorithm to encrypt/decrypt,
    it works fine across machines, since i am not using a Facrtory to create the secret .
    i am using constant SecretKeySpec and iv for the ciphers.
    this of course heart the security , and doesn't prevent the "man of the middle" problem .
    i saw that there are ways with key generation with MAC , and RSA symmetric encryption , but i am not sure
    how to implement it , and how to it depends on local certificates or files .
    i have searched for an complete example , but in vain.
    please help

    Welcome to the Forum! Please read this topic to learn how to post code correctly and other useful tips for newcomers.

    What's your question? Can you state it in one or two sentences, possibly with one of them ending in a question mark, maybe both?

    Thanks.

    i didn't post code ....
    i just asked a question....
    i need a good,encrypted way , that does not use a constant string for the secret key (that is needed for the SecretKeySpec).
    i saw that there is the RSA way (keyPair generation) and the MAC way (generate some key too .
    the question is : if i generate a key is the machine that does encryption - then in the decrypting machine i won't be able to decrypt it .
    i will need the key .
    so - what is the better way to generate some random key , but still be able to decrypt it on another machine ? (question mark...:-))
