Is there any way to encrypt a text in automagic?
Suppose I want to forward OTP messages I receive on one phone to another phone, and I want that text to be encrypted with a passphrase before sending. Is this possible using some command line or something?

Re: Automagic encryption
I have requested the feature here : viewtopic.php?f=4&t=7892
Maybe anuraag can help with the java method to use the common used encryption, such as AES 128 bit.
You can implement your own personal encryption algorithm. But since you can't test the strength, it is better to use the widely known encryption which has been prooftested to be strong enough from many kinds of decryption attack. Wrong implemented encryption can lead to false sense of security, which is worse than have no security at all.

Here is a flow to encrypt text based on https://github.com/pasha656/Crypto/blob ... rypto.java

Re: Automagic encryption
@anuraag : thank you, this can be used to safely transmit data on public feature, example using public MQTT server (everyone can see the message, but they can't read decrypt it)
I try with the encrypt/decrypt, it works well. However I am usually skeptic and always need double check. I try the encrypted text in the online website, put in my password and can't decrypt it. example, this is "hello word' with the password "123"
Example website to decrypt https://www.devglan.com/online-tools/ae ... decryption
It says the secret key must be 32 byte for the 256 bit AES.

Re: Automagic encryption
@desmanto There may be some problem with that site. That site can't even create a encrypted text.
I think encrypted text created using my posted script can't be decrypted with other tools unless both uses same method. For example i am using "]" as delimiter, Autotools uses ":" (autotools uses different method to encrypt i guess this https://github.com/tozny/java-aes-crypt ... grity.java).

Re: Automagic encryption
@anuraag : Hmmm, I am thinking to store some of my private stuff in encrypted mode. But I need it to be universal standard. So if I don't have access to automagic, I can still decrypt the file/text. I wonder how most website/banking or other security system implement this.

Re: Automagic encryption
Do you know any reference which defines universal standard or any other tools which works across platforms?
Re: Automagic encryption
I previously use SSE - File/Text Encryption for some stuff : https://play.google.com/store/apps/deta ... ndroid.sse
But since I don't need it anymore, uninstalled. At that I don't need universal decryption method yet, so I just trust the app alone, it is open source.
I might look at it again this weekend, testing the decryption on serveral websites. I just changed ROM and there are several flow need to be adjusted.
