NETCore.Encrypt.OutofMaxlengthException trying to encrypt 123 #27

Do you know why var encrypted = EncryptProvider.RSAEncrypt(publicKey, "123");

Retrieves: {"Exception of type 'NETCore.Encrypt.OutofMaxlengthException' was thrown."}

publicKey:

        private const string publicKey =
        @"{""Modulus"": ""m9c88+sazyrDZv7Amrek2MCkkx0ZkHfWXCCPZuZwT8gKEH4m/VDKj6hTVNr0GbZy8ZKtiq9NAxoS5Vr+xdsE9mVJu7XmU/s+D1GnF3cubckivKzCvs63sQQ9JpGmrOkIlfGbmGUprO0HEt3FA2fua/nGh67ApyLPykYXjMQI5QE="",
""Exponent"": ""AQAB""}";

You can try to specify the RSAEncryptionPadding, the default value is RSAEncryptionPadding.OaepSHA512.

var encrypted = EncryptProvider.RSAEncrypt(key, srcString, RSAEncryptionPadding.Pkcs1);

Can I use nopadding - Is it safe?

Do you if it is possible to decrypt/encrypt data using PEM private/public keys?
