SecureBlackbox.NET is a powerful component collection that provides advanced security functionalities like SFTP, FTPS, SSH, SSL/TLS, PKI, EDI, and more to .NET, Xamarin, Mono, or .NET CF applications. With its cloud and Office support, it ensures complete security for your data, documents, and communications.

SFTPBlackbox enables users to securely transfer files and perform remote file system operations using the SSH File Transfer Protocol (SFTP). Users can also create their own SFTP servers to facilitate secure data transfers.
SSHBlackbox, on the other hand, allows users to access remote SSH servers using SSH protocols. It's also possible to build and run one's own SSH server.
FTPSBlackbox makes it possible to transfer files securely using both the FTP (RFC 959) and FTP-over-SSL protocols. Users can also create their own FTP or FTPS servers to facilitate secure file transfer operations.
HTTPBlackbox facilitates secure web access and allows users to access web sites via HTTP and HTTPS protocols inclusive of Gzip compression. The software further enables users to create their own HTTPS servers or proxy servers.
OpenPGPBlackbox enables users to encrypt and sign files using OpenPGP algorithms and standards. It also provides users with the ability to generate and manage OpenPGP keys and keyrings.
XMLBlackbox allows users to encrypt, sign, and timestamp XML files or generic data using XML encryption and signing standards such as XMLEnc, XMLDSig, and XAdES.
PDFBlackbox enables users to compress, encrypt, sign, and timestamp PDF files using the PDF and PAdES standards.
SSLBlackbox provides support for SSL and TLS 1.0-1.2 protocols for both clients and servers. It also features Datagram TLS (DTLS) support.
MIMEBlackbox enables users to compose and parse MIME messages with optional S/MIME or PGP/MIME.
MailBlackbox facilitates the sending and receiving of e-mail through SMTP, POP3, and IMAP protocols.
PKIBlackbox provides the full scope of PKI and X.509 certificate management functions to users.
EDIBlackbox facilitates the exchange of business information through the AS2 and AS3 protocols.
ZIPBlackbox enables users to compress and decompress data with strong encryption.
CloudBlackbox allows for secure data storage in cloud storages.
OfficeBlackbox provides users with the ability to encrypt or digitally sign Office documents.
WebDAVBlackbox makes it possible to access and manage resources using WebDAV.
SAMLBlackbox enables users to create SAML authentication clients and servers.
ASiCBlackbox provides data signing capabilities using the European standard for Associated Signature Containers (ASiC).
