Issue Description and Steps

Encode with RS256 using string data of a private key, but I got error Error Domain=NSOSStatusErrorDomain Code=-50 "RSA private key creation from data failed" UserInfo={numberOfErrorsDeep=0, NSDescription=RSA private key creation from data failed}

Here is code sample:

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"example" ofType:@"key"];
    NSString *key = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

    NSDictionary *payload = @{@"payload" : @"hidden_information"};

    id <JWTAlgorithmDataHolderProtocol> signDataHolder = [JWTAlgorithmRSFamilyDataHolder new]
            .keyExtractorType([JWTCryptoKeyExtractor privateKeyWithPEMBase64].type)
            .privateKeyCertificatePassphrase(nil)
            .algorithmName(JWTAlgorithmNameRS256).secret(key);

    JWTCodingResultType *result = [JWTEncodingBuilder encodePayload:payload]
        .addHolder(signDataHolder)
        .result;

    NSString *token = result.successResult.encoded;
    NSError *error = result.errorResult.error;

    NSLog(@"%@", token);
    NSLog(@"%@", error);```

Could anyone here help me regard this issue, please? 🙏

Are you sure that this is a valid RSA key?

OpenSSL can't extract public key from it.

openssl rsa -in private.pem -pubout > public.pem

@lolgear
I generate RSA keypair with command below: openssl req -newkey rsa:2048 -nodes -keyout private.key -x509 -days 365 -out public.crt

@sambo-nbc Try to regenerate key and extract its public part.

openssl req -newkey rsa:2048 -nodes -keyout private.key -x509 -days 365 -out public.crt
openssl rsa -in private.pem -pubout > public.pem

It should work.
