Support the eth_getEncryptionPublicKey and eth_decrypt methods

[dysbulic]

Describe the usability problem

Version 8 of the Metamask browser extension added eth_getEncryptionPublicKey to return a Curve25519 encryption key derived from the account's private key. Also, it added eth_decrypt to decrypt information encrypted with the aforementioned public key.

This page demonstrates the functionality in brief.

Expected behavior

These functions are not available in the mobile version. It would be very useful for my application is they were.

Hi, is there any timeline for this feature yet?

[rstormsf]

We need this feature for our mobile users.

[dysbulic]

Depending on the flexibility of your app, IDX has the ability to generate cyphertexts (JWEs) with keys associated with a $ETH account.

@mrenoon, no timeline yet. We'll update here when we plan for it. Curious to hear which dapp you are working on, and how you intend to use the eth_getEncryptionPublicKey & eth_decrypt methods (your use-case / context of the app where this will be useful)

[rstormsf]

@omnat Currently, app.tornado.cash uses both methods for storing encrypted private key on-chain. Encryption happens with metamask's public key for recovery.

[boyuanx]

Our dApp (EthSign.xyz) also plans to use it to encrypt and decrypt AES keys that encrypt and decrypt various documents stored on IPFS.

This feature would be extremely useful for my mobile dapp project. Is there any progress on making this available for metamask mobile?

[ArcQ]

is this in the roadmap? we would love this feature as well

[shawnmitchell]

Yes please! Parity with the browser extension with respect to this functionality would be most appreciated!

[joshuaohana]

Would also love this feature on mobile. I use this to enable users to keep private data onchain and decrypt only with their private keys - makes my app unusable on mobile without it...

[amilich]

Same!

[ghost]

Our app on web is using eth_decrypt to decipher files. Would be amazing to have it working on mobile as well.

[jdbertron]

Hello ? Can we get some feedback for when this will be on the roadmap ?

[avivash]

hi @omnat 👋🏼, has any progress been made on this? I need this for a Dapp I'm currently working on. Thanks!

[davigp]

same here, we are limited to desktop experience 🙁

curious about how we could help to implement eth_getEncryptionPublicKey for mobile

[prtk418]

Is this feature being worked on?

[avivash]

Folks from brave, metamask and various other CASA members are discussing a chain agnostic way to implement this for all wallet clients here:

https://github.com/ChainAgnostic/CAIPs/issues/132

and more actively here https://ethereum-magicians.org/t/eip-5630-encryption-and-decryption/10761/112

[mostafaamr137]

Hello ? Can we get some feedback for if this feature will ever be implemented ?

These two methods are still not supported now, is it possible to support them in the future.

[mark-smartseal]

Would really love it if they were. It would be incredibly useful
