Encryption using public key from eth_getEncryptionPublicKey metamask function

Question

I'm trying to encrypt data/files before uploading them to IPFS and I want to do this using metamask provided public and private keys. For this, I have tried using eth_getEncryptionPublicKey but this gives me a public key of length 48 characters which is similar to ZvpXeyKc1iJbidfr0TL7BAmyofkCdaPUvVvcDI/FEWc= also I'm using vanilla js so can't find a way to use eth-sig-util

Can someone suggest some algorithm that supports this public key length or help me use eth-sig-util into js
