I'm looking for a transportable file or folder locking program?

Question

hello, I'm trying to find a utility that will password lock, protect, or encrypt a single file. but the utility must be portable, as in i need to be able to password-lock a file, transfer it to an SD card or flash drive, transport it to another computer and open it WITHOUT the password protection software. any ideas? thanks for the help

Cryptainer LE enables you to create a secure container on your PC, using powerful 128 bit strong encryption - without changing the way you work. The software creates new virtual drive letter(s), and all files that are added to this drive are encrypted on-the-fly. You can also create a secure storage container on any media including external and removable drives (e.g. USB drives, CD etc). The drive letter is accessible through Windows Explorer just like any other drive - as long as you are logged into the Cryptainer PE interface. If the program is terminated, the files in the secure drive are no longer accessible to other users - you can access them at any time by logging in with your password. Using this method, you can automatically keep a secure area, that can only be accessed by you, without having to encrypt individual files manually - just login once. In addition, Cryptainer LE allows you to send files with encrypted email messages, using self-decrypting EXE attachments that do not require any software to be installed by the recipient. The free version is limited to a container size of 25 mb, however you can create an unlimited number of such 25 mb containers.
