Issue Description and Steps

I have simply copied the example code:

NSDictionary *payload = @{@"payload" : @"hidden_information"};
NSString *algorithmName = @"RS256";

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"secret_key" ofType:@"p12"];
NSData *privateKeySecretData = [NSData dataWithContentsOfFile:filePath];

NSString *passphraseForPrivateKey = @"secret";

JWTBuilder *builder = [JWTBuilder encodePayload:payload].secretData(privateKeySecretData).privateKeyCertificatePassphrase(passphraseForPrivateKey).algorithmName(algorithmName);
NSString *token = builder.encode;

Instead of having a p12 file I have a sting of a secret key. Something like that:

"-----BEGIN RSA PRIVATE KEY-----\nMIIEpAIBAAKCAQEAtN7LQq7l9a9....SUug==\n-----END RSA PRIVATE KEY-----\n"

Is there a way to implement the string with this library?

Thanks in advance.
