I'm retrieving a public key from KMS using the javascript SDK. The result has the property PublicKey
which is of type Uint8Array
. I'm verifying a token using the jsonwebtoken
library. I'm not verifying the token with the KMS SDK because I'm implementing a microservice architecture and the signing and verification happen in different services so my verification code does not have access to the Signature
returned by the sign
method on the KMS client.
Back to the KMS client, the result has the property PublicKey
which is of type Uint8Array
. This can be converted to a string with the following code Buffer.from(result.PublicKey).toString('base64')
. This does not follow a verifiable format however.
I'm expecting to see the string formatted as '-----BEGIN RSA PUBLIC KEY-----foo foo foo'
with the appropriate header and footer. When I parse the public key, however, I'm only receiving the body and not the header and footer of the public key.
How can I receive the header and footer in getting the public key from KMS?
