Can we generate RSA public key from PEM? #22

Closed adonese closed 3 years ago

adonese commented 3 years ago

Currently the library only generates a random RSA key and use it for encryption. Some use cases (my current use case) relies on an existing rsa public key, and the idea is to use the existing public key to encrypt a message.

Can this use case be supported? Thanks!

Technically you could use the RSAPrivateKey.fromString Function for that. But I could add a .fromPEM function.

Unfortunately, i'm not that good in dart / flutter -- and you can correct me if i'm wrong. This library is testable by flutter test and unlike other libraries, it doesn't rely on OS specific functionality for that.

That's why i think it is cool, plus also the simple API too!

PS. Can that by RSAPublic.fromString()?

No worries, I created this lib to make Encryption easy and accessible for everyone :)

Yes, thanks to Dart this lib is platform-independent. To test this lib you simply clone the repo and run pub test

To create a public key using a string you could use RSAPublic.fromString()

You can also look at the API Dokumentation for more information.

So great! I used RSAPublic.fromString() and it just worked!
