Encryption Decryption

  • i have been asked to write a program which will encrypt an text file.

    iam coding in vb

    till now i haven't been able to find any code, which will help me..

    if any knows the solution

    pls post

    iam using file system object to read and write strings from the text file

    and encryption code should use "advapi32.dll"

    no third party tool

  • Most encryption mechanisms will result in character codes you wouldn't normally find in a text stream. What encyption algorithms have you tried and how have you tried to read to/write from the file (what FSO methods)?

  • I haven't read the article yet, but today this site had an article on encryption and SQL Server. Perhaps it would be useful. It has what appears to be some good references.

    I would strongly suggest a good third-party tool (not that I can recommend one off-hand). Mainly because that using a proven algorithm is always better than trying to write your own as it has normally been subjected to scrutiny and attack.
