PKCS extensions for .Net Standard, .Net Core and Blazor BCL without external dependencies.
Code is focused for AOT compilation, IL linking and using with Blazor (small library, avoid reflection, minimalize internal code dependencies).


  • Namespace PkcsExtensions:
    • ECDsaExtensions - export keys to DER/PEM format on ECDsa.
    • HashAlgorithmConvertor - convert HashAlgorithmName to OID, implementation,...
    • HexConvertor - convert from/to hexadecimal.
    • PemFormater - helper class to convert DER to PEM and back.
    • RSAExtensions - export keys to DER/PEM format on RSA.
    • SecureStringHelper - safe provide SecureString.
  • Namespace PkcsExtensions.Algorithms:
    • DigestRandomGenerator - Secure random generator based on hash algorithm (inspired from Bauncy Castle). Is helpful for password generation and entropy collection.
    • HashAlgorithmExtensions - More friendly extensions for HashAlgorithm types.
    • RngRandomGenerator - wrapper to RandomNumberGenerator
    • SP800_108 - Standard KDF function in counter mode (inspired from Inferno library).
  • Namespace PkcsExtensions.ASN1 - ASN.1 writer and reader from Microsoft corefx repository.
  • Namespace PkcsExtensions.Pkcs1:
    • Pkcs1DigestInfo - Is helpful for RSA signing using SmartCards through PKCS#11.
  • Namespace PkcsExtensions.Pkcs7 - Missing features for SignedCms.
  • Namespace PkcsExtensions.X509Certificates:
    • X509Certificate2Extensions - X509Certificate2 extensions for determine the usage of certificate.
    • X509Certificate2EncodeExtensions - encode (DER/PEM) extension for X509Certificate2
    • X509Certificate2NameInfoExtensions - X509Certificate2 extensions for extract values by OID from isser and subject name - method GetNameInfo.
