encodePublicKeyToPemPKCS1 method
Encode Public key to PEM Format
Given RSAPublicKey
returns a base64 encoded String with standard PEM headers and footers
Implementation
String encodePublicKeyToPemPKCS1(RSAPublicKey publicKey) {
var topLevel = new ASN1Sequence();
topLevel.add(ASN1Integer(publicKey.modulus!));
topLevel.add(ASN1Integer(publicKey.exponent!));
var dataBase64 = base64.encode(topLevel.encodedBytes);
return """-----BEGIN RSA PUBLIC KEY-----\r\n$dataBase64\r\n-----END RSA PUBLIC KEY-----""";
}
