Converting web3Storage CIDv1 to 32 bytes string to fit ASA standard (Algorand asset standard)
import CID from 'cids';
function hexToBase64(hexStr) {
let base64 = "";
for (let i = 0; i < hexStr.length; i++) {
base64 += !((i - 1) & 1)
? String.fromCharCode(parseInt(hexStr.substring(i - 1, i + 1), 16))
: "";
}
return btoa(base64);
const hex = new CID(cid).toString('base16').substring(9)
let base64 = hexToBase64(hex);
const buffer = Buffer.from(base64, "base64");
const response = JSON.stringify({
base64: base64,
hex: hex,
buffer: buffer.length
});
