Simple encryption

TXTcrypt is a general purpose text encryption application for sms/email/notes etc. focused on ease of use and interoperability between mobile and desktop versions.

You can use it for text in any application , including text from the TXTcrypt desktop application.

Say you want to send a sms that only someone knowing a password for it can understand , or just need to encrypt a conversation to hide it for prying eyes , now there is a easy way for that on a iphone.

With TXTcrypt just enter your message and a password for it , now the encrypted message can only be decoded with that password , just tell it to someone , and send them message encrypted with it , they can use TXTcrypt to decode it.

TXTcrypt works with any character set being unicode compliant , the encryption used is as strong as encryption export regulations allow , not military grade but namely RC4 with keys as big as 64bit depending on the length of your password as such providing a decent amount of security.

Still best in class for its price

3/12 Still one of the most functional for free. 256 AES would be ideal but this level of encryption suffices. Would love to see upgrade/dev support.

Original: Thanks dev for this app. It's BY FAR superior to all free and most paid alternatives. Compatible on iPhone, iPad and desktop companion version (all free) makes it very easy to use everywhere for most everyone you know. Simple UI makes it easy to SMS and email from app. I'd pay a reasonable amount for an upgraded with expanded features but as-is this is a valuable tool for most lower grade everyday encryption communication needs. 👍

For daily routine comms you want to keep private-this is the app. Not high grade as previous reviewer states but more than adequate. My only complaint is the background color of white. Makes it difficult to differentiate text vs email.

iPhone X fail

It works to send txt, however, when I receive an encrypted txt, after I put in the password and hit decrypt, it kicks me out of the app!!!!
