Ever wanted to send a text message or SMS that only you and your recipient can understand? Need to send confidential information via SMS, safe from anyone's prying eyes?
Encrypt SMS is a tool that allows you to encrypt messages that you send out with a password, and only those that have the same password can successfully decrypt and read the messages. (Recipient must have the same application on their iPhone.)
Encrypt SMS uses AES-256 encryption, a military-grade encryption composed of a 256 bit key to ensure that it will not be easily broken. The US government itself uses AES encryption to secure classified information! You too can have access to this high level of security with Encrypt SMS.

Ratings and Reviews
Simple, deterministic crypto app.
App does PKCS#5 padding, then performs AES-256-CBC with an IV of all zeros. Password is null-padded to serve as key; no key strengthening is done.
App probably needs to be used in conjunction with a password manager in order to make a long enough password feasible. (You might want a password of up to 32 characters.)
iMessage integration would be nice.
Does not work, DO NOT waste your money
Up to six family members will be able to use this app with Family Sharing enabled.
