If I use an encryption program to encrypt a file with a standard algorithm (blowfish, e.g.), can a different encryption program successfully decrypt the file?
I might start using an old encryption program like Scramdisk or E4M and want to know if I can use another program in future to decrypt the files, supposing that I lose the old program and it is no longer available for download anywhere.

If the decrypter uses the same Algorithm, key, and is provided with a proper password(if one was set) then yes. Unless you encrypted the file with Steganography, then you must use a steganography program to decrytp it and unhide the files.

It should work depending on the version of the program that you would use to decrypt the file(s). Therefore if you have a very advanced algorithm you'll need a updated version of (ex: blowfish) but really I think it shouldn't matter… Good luck!
