Compucourt Internet/FTP Servers utilise Secure Shell
(SSH-2). This allows a secure connection channel between a local and a remote computer. It uses public-key cryptography to authenticate the remote computer and (optionally) to allow the remote computer to authenticate the user.
Files are then transferred using SSH File Transfer Protocol (SFTP). Compucourt
software also incorporates its own encryption written by our programmers. Using
binary phase shifting algorithms, files/messages are encrypted before sending
and decrypted when received. This assures confidentiality and integrity of data exchanged between the two computers.
For additional security we can
supply Pretty Good Privacy Security (PGP) or
(Linux GnuPG) keys. PGP encryption uses
public-key cryptography to create public and private keys for each user
identity. Asymmetric key encryption algorithms for email and a symmetric cipher
algorithm allows for the sender to use the recipient's public key to encrypt a
shared public key. This shared key then encrypts the plaintext of a message. The
end-user must either have PGP or GnuPG (Windows or Linux platform) compatible
software installed. We are versatile in regard to Key
Strength and length and can meet any level of security required by the end-user.
Compucourt DMZ and Proxy Servers provide
for additional security and firewall between local and wide area networks.
