// RsaKeyParser extracts private key from a pem string
final parser = RsaKeyParser();
final rsaPrivateKey = parser.extractPrivateKey(pemPrivateKey);

// Create RsaSignifier for signing
final rsaSignifier = RsaSignifier(privateKey: rsaPrivateKey);

// JwtBuilder encodes the token to string and signs it
