AXCrypt
Using the context menu, I first tried to encrypt a copy of a directory - this seemed to be doing something - but I'd no idea where it put the encrypted file!
I then tried encrypting in place - the program seemed to stop at shredding the first file.
Eventually it dawned that the program does not created archives - it was encrypting each file in the directory.
In use, it does what its suppoed to. As with 7zip it uses a temporary directory to store the unencrypted file. In some circumstances it seems to have problems deleting the file when the application is finished with it - but it does promise to delete it the next time the computer is started up. This seems to be related to an existing process opening the file (start up MS Excel, open another doc, then open a axx doc).
Saving a modified file caused errors, but subsequently reopening the file from axcrypt it kept the changes.
Its ugly, but fairly fool proof.
CryptonIt
CryptonIt uses asymmetric encryption - and we have no PKI infrastructure. But looks like a worthy successor to the delisted WinCrypt freeware (still available from other sources on the internet).
LockDisk
LockDisk looks interesting but the developers are very vague about the licence and the algorithm.
BladeBox
BladeBox creates a virtual drive (no temp files?) the site claims AES encrpytion but licence terms are not published. Variously listed as shareware and freeware.
CryptoExpertLite
CryptoExpertLite is another virtual drive - nice gui but no dynamic sizing of the drive.
I should point out that I was just joking about the CamelCase thing in my previous post - it seems to be coincidence that all the products which seem to come close to matching my brief
have CamelCase names.
