Hi all,
I have found the following major security issues with all the encryption software I have tried thus far:
1.
The original encrypted file is decrypted when using the software by entering the encryption password, and when shutting down the app the file is re-encrypted. However, in the event of an unexpected termination of the software (power loss, battery failure, app crash, etc.) the app does not re-encrypt the decrypted file (and cannot re-encrypt it, as it has terminated unexpectedly), and it thus sits there on your hard drive in unencrypted form until you hopefully notice that it didn't get re-encrypted.
2.
Upon entering the decryption password, the software creates a temporary file copy of the decrypted file and stores it in AppData or Temp or some other place, leaving the original file safely encrypted. However, in the event of an unexpected termination of the software (power loss, battery failure, app crash, etc.) the app does not delete this temporary file (and cannot delete it, since it has terminated unexpectedly), and it thus the temp file sits there on your hard drive in unencrypted form until you hopefully notice that it didn't get deleted.
Additionally, almost all apps seem to require an online sign-in, which I don't want either.
In summary, I'm looking for encryption software which meets the following requirements:
1. Can encrypt selected files//folders, and does not require entire partitions/drives to be encrypted.
2. Does not suffer the above problems from unexpected shutdowns. Veracrypt for example gets around this by only opening files in RAM (in unencrypted form). No temp files etc. The problem with Veracypt, as I understand it, is that you can't encrypt selected files and folders around your hard drive. You have to encrypt a whole drive.
3. Encrypts and decrypts locally. No internet connection or sign-in to company servers required.
4. Open source.
5. Available on Windows.
Preferably the following if possible:
6. Automatically re-encrypts open files if lockscreen is shown, or is PC goes to sleep or hibernates.
7. Re-encrypts automatically after optional time period eg. 5 hours.
8. Portable version available.
Thanks for any suggestions.
