Free 256 bit aes software for windows

RemoteNote Lite 1 is regarded as a full featured and advanced solution to the problem of organizing, securing, and centralizing your essential data, reminders, passwords, links, to-do lists and sticky notes without the hassle and limitations of a typical PIM application.

RemoteNote runs as a powerful, yet easy to use desktop/taskbar widget which allows you access to your securely stored information on the Web with a single keystroke. RemoteNote helps you organize your data into top-level, floating, color-coded categories, subcategories, and sticky notes for easy access. Since only you hold the keys to your highly secure 256-bit AES encrypted data it is nearly impossible for your private stores to be compromised. RemoteNote also allows you to securely share any of your notes or category with other subscribers via highly secure 2048 bit RSA encryption.

fSekrit - easily read and edit encrypted notes in their own portable executables fSekrit is a small application for keeping encrypted notes. The real advantage of fSekrit is that notes are truly self-contained; the editor program and your note are merged together into a tiny self-contained program file, removing the need to install a special application to view your data. This makes fSekrit ideal for keeping encrypted notes on, for example, USB flash drives.
Another advantage of using fSekrit is that your un-encrypted data is never stored on your harddisk. With a traditional encryption utility you would have to decrypt the file to disk, view or edit it and then re-encrypt it and unless you use secure file wiping programs, it would be a trivial matter for someone to retrieve your un-encrypted data, even though you has been deleted. This cant be done with fSekrit, though, since it never stores your un-encrypted data on disk.
fSekrit uses very strong encryption (256-bit AES/Rijndael in CBC mode) to ensure that your data is never at risk. Self contained fSekrit notefiles are tiny ! Only 40k plus the size of your text.
Your unencrypted data is never stored to disk by fSekrit. It is, however, stored in memory (otherwise you wouldnt be able to view or edit it .
This means that windows, in case of low memory, might choose to swap it out to disk, in which case a malicious hacker with access to your computer could snoop it from your paging file. So, avoid running fSekrit in low-memory situations (i.e. dont keep it open while playing 3D games or using photoshop).
The 256-bit AES encryption key is constructed directly as an SHA-256 hash of your passphrase.
When you use file->save, some tricks have to used, since windows will not let an application write to its own .exe file (or in fact any .exe file that is currently running). Thus, fSekrit makes a copy of itself with the newly saved data, launches this temp file that copies itself to the main file, and launch the main file again to delete the temp file. This is why the main window goes in and out of existance briefly when you save.
To avoid re-entering your passphrase every time you save, fSekrit passes your encryption key on the commandline. But note that your passphrase is never passed on the commandline, so simple snooping cannot reveal it.
A skilled malicious person *could* theoretically snoop the key and use it to decrypt your data though, so be cautious when running fSekrit on systems you dont trust. However if you are using a computer you dont trust then there are more serious risks to worry about, such as the possibility that there are keyloggers running, which would record your passphrase without the complexity that key snooping would require.
The fSekrit executable is compressed using Jeremy Collakes PECompact2, which chopped merrily away at the original ~76k filesize before compression.
To identify whether a correct passphrase has been entered, a SHA-256 hash of the original plaintext is stored in the file header. This is not a security risk as your data cannot be reconstructed from the hash.
