Asymmetric Encryption and Decryption

[joaosantos15]

From what I understand, js-libp2p-crypto is the JS implementation of go-libp2p-crypto and uses the WebCrypto API whenever possible.
For asymmetric encryption/decryption, go-libp2p-crypto uses RSASSA-PKCS1-v1_5, which is only supported for digital signature by the WebCrypto API.
On the other hand, the only asymetric encryption supported by WebCrypto API is RSA-OAEP.

It would be nice to have RSA encryption in js-libp2p-crypto ☀️.

What would be the way to do it? Use the WebCrypto API's RSA-OAEP or implement go-libp2p-crypto's RSASSA-PKCS1-v1_5?
Thanks!

• If we add RSA encryption, we want to match what go does for full interop.
• Ideally we would add encryption and decryption to all supported key types in one go, but this is not a requirement.
• we already use node-forge for some operations, so you could use it for doing the RSA encryption/decryption

Oh hey @joaosantos15 , five months ago I developed this package that does decryption and encryption natively in Nodejs. Kind of a wrapper package that makes RSA Keypair encryption and encryption easier in terms of coding syntax:

https://www.npmjs.com/package/quick-encrypt

Not sure if it might be of help to you haha!
