The class @Lacuna.Pki.PKCertificate provides viewing and manipulation of X509 certificate information. The class supports the loading of certificates with BER, DER, Base64 or PEM encoding.

PKCertificate PKCertificate.Decode(byte[] certContent);

// Para certificados com encoding Base64 ou PEM
PKCertificate PKCertificate.Decode(string certContent);
```
