custom encryption and decryption

ho dudes.

i wanna make some custom encryption functions to stop people snooping at my data. i dont wanna use aes or the other ones.

btw, i think that i may need the encryption template, when i saw through some crypto code.

can someone help with good code?

  • I really dont think its right forum to post this question but since you have worked extensively in this domain your inputs would be of great help.

    Requirement: Avoiding repeated decryption of file/data
    Expected behavior of Algorithm:

    Example: consider file(f0) on encryption gives encrypted file(ef0) and key(ek0) i.e
    f0 ----> ef0 and ek0.(repeating encryption of encrypted data)
    ef0 ----> ef1 and ek1.
    ef1 ----> ef2 and ek2.
    . .
    . efn-1 ----> efn and ekn.

    On applying decryption on efn using ekn I should be able to get f0 bypassing decryption of (efn-1, ...ef2, ef1). Hence key is expected to have delta value during each successive encryption.

    Is there any encryption and decryption algorithm currently displaying this behavior?

    Looking forward for your suggestion.
