Trust

I no longer trust the easy online wallets for passwords and codes. I use PTE and rotation passwords and have for the last couple of years. My ID has been robbed at least 3 times through data breaches hitting the US gov and other places. TRUST no one. Encrypt your sensitive data yourself. Freeze your credit history.

Great app

Straightforward text encryption with multiple variations of method. I also love the added feature of hiding text in pictures.

Great job.

Very cool indeed.

disappointed

"upgrading" to Monterey destroyed my ability to use 90% of my legacy software, including iStego. While searching for any free steganography software that was free and usable on my now crippled mac mini (thanks for nothing Monterey), this Paranoia Text Encryption software claimed it could do steganography. Instead of conveniently letting you drop a file of your choice onto an image of your choice and ending up with a file hidden in an image with little fuss, PTE makes it practically impossible. Perhaps someone will figure it out, but my patience wore thin and I gave up after wasting time. Not intuitive or user friendly, and not worth the time I wasted trying to get it to work.

Response from developer

This is (as the name suggests) text encryption software. If you want to work with general files, I would recommend looking for something like FILE encryption/steganography.

Not For Infrequent Users

Each time i use this i type a bunch of great ideas, then proceed to irretrievably lose everything I types - zilch! The terrible part about this program is it is not prepared for people like me that has not memorized all the controls and don’t realize that after i create encrypted text and i think im cleaning up the readable text so i hit the broom, and EVERYTHING I JUST TYPED IS IRRETRIEVABLY GONE WITHOUT ANY WARNING, so its my fault that it doesnt have safeguards for human operators. So, not for me.
