  • When error : > key invalid : illegal key size or default parameters Go to oracle.com and search for : Java Cryptography Extension (JCE) "Accept" to download jce_policy-8.zip Unzip and place it into .../jre/lib/security/

  • The portable version is not capable of importing old PGP keypairs. Further, it requires an additional install of Java(TM) Cryptography Extension, or generating a keypair will fail. The automated windows installer does not check or ask if there is a java installed and running and downloads a JRE without asking. Unwanted behavior! Rated because it is required, have not yet tried the program.

  • I agree with the reviewer about the weakness in only allowing 1024 bit keys and the weakness in using ElGamal as the alternative. However, I can generate keys elsewhere (a very infrequent need) and importing these keys is a snap. The most important function to me is that it can encrypt/decrypt conveniently and this it most certainly does. Despite the downside, I'm giving it 4 stars because there's a workaround for the weakness and it's not the major function..

  • Works great - super easy alternative when I am on the go and don't have any other method to encrypt and decrypt a file.

  • I would have loved this software. Small size for standalone edition and works on many systems. Unfortunately it dostn give many options regarding Key size and only allow Elgamel which i believe my search has revealed has been compromised. And ontop of that it seems keys with only 1024bit encryption has been to easy to break on modern day computer according to forums. Updating to 4096bit key and possibility to use a better option than Elgamel would be a sure 4/5 star software simply for being portable/safe.
