To make it work in 4.4+ install following app:
Then give ECC SMS "writing sms" permissions.
Made for encryption lovers!
with Elliptic Curve Cryptography.
- totally over sms
- public-key infrastructure (PKI)
- Elliptic Curve Integrated Encryption Scheme (ECIES)
- equals >15360bit RSA Encryption!
- protects efficiently until year 2120
This means that after 2120 there may be enought computational power on earth to find the private key for decrypting the messages in a useful time.
Key sharing works like in PGP SMS.
Because of the strong ecryption, it needs at least 2 sms for a single conversation.
Attention: Currently some cyanogenmod nightlies have an error while sending multipart sms messages.
- more compatibility
