PC-Duo overview

transparent every time two PC-Duo 5.20 components or later are communicating with

each other.

By default, PC-Duo Express and PC-Duo Enterprise uses AES 256-bit encryption,

however other encryption options can be set, including:

 AES encryption (256-bit key) with SHA1 hash

 AES encryption (192-bit key) with SHA1 hash

 AES encryption (128-bit key) with SHA1 hash

 Triple-DES (3DES) encryption (192-bit key) with SHA1 hash

 RC4-compatible encryption (128-bit key) with MD5 hash

NOTE: PC-Duo 5.10 applications and older support only RC4 encryption; thus, this would be the

encrpytion option negotiated between a PC-Duo 5.20 or later application (e.g. PC-Duo Master)

and PC-Duo 5.10 application (e.g. PC-Duo Host).

Order of precedence

When two PC-Duo components have different encryption options set, the first encryption

choice in common between the two is used (going down the list in order), with preference

set as follows:

 Preference set by the Host, when the Gateway requests connection to the Host

 Preference set by the Gateway, when the Master requests connection to a Host

through the Gateway
