Cryptographic Helpers

Sign Payload

Signs a given string payload using a base64-encoded RSA private key.

import { signPayload } from '@pcse/fiat-sdk';

const signature = await signPayload({
  payload: JSON.stringify({ amount: 1000 }),
  privateKey: 'BASE64_ENCODED_PRIVATE_KEY',
});

Verify Payload Signature

Verifies the signature of a payload using a base64-encoded RSA public key.

import { verifyPayloadSignature} from '@pcse/fiat-sdk';

const isValid = await verifyPayloadSignature({
  payload: JSON.stringify({ amount: 1000 }),
  signature: 'GENERATED_SIGNATURE',
  publicKey: 'BASE64_ENCODED_PUBLIC_KEY',
});
