Self-destruct-o is like One-Time Secret on steroids, while read-once doesn’t even try to protect the message or password it uses.
PrismCipher does not store protected data on servers like self-destruct-o or One-Time Secret, neither does it transmit a plaintext password over the air like read-once does. Services such as One-Time Secret are good for creating protected data shares and, once protected, you choose how to send the data to the intended recipient.
PrismCipher is good for seamlessly transmitting data over existing services like LinkedIn, Yahoo or Gmail. Once you encrypt, you can see exactly what you’re sending prior to transmission.
