Encryption property


Determines the level of compression used.

Type

An EncryptionsEnum enumeration.

Syntax

  • Basic
object.Encryption [= value]  
The Encryption(object,value) syntax has these parts:
objectAn expression evaluating to an object of type wodTunnel.
valueAn EncryptionsEnum enumeration, as described in settings.

Remarks

The settings for Action are:

Constant Value Description
encAny0 Anything suitable, selected by wodSSHTunnel component.
encDES 1 DES encryption
enc3DES2 3DES encryption
encAES 3 AES encryption
encBLOWFISH4 BLOWFISH encryption
encAES128 5 AES 128bit encryption
encAES1926 AES 192bit encryption
encAES256 7 AES 256bit encryption
encCAST1288 CAST 128 encryption


During negotiation of a secure connection between wodSSHTunnel and a remote server, when set to anything other than encAny, wodSSHTunnel will only allow the specified encryption algorithm to be used for encrypted data transmission. If this property is set to encAny (as it is by default), any encryption known by both wodSSHTunnel and the remote server may be used.

wodSSHTunnel's implementation forces selection of encryption algorithms (for encAny value) in this order:

  1. For an SSH1 connection it will try to negotiate the TripleDES algorithm. If it fails, it will try Blowfish. If this is not available (on the remote server), it will fallback to DES. Please note that the DES algorithm has been declared 'insecure', so you should avoid using it if possible.
  2. For an SSH2 connection it will attempt to negotiate AES (any type) first. If it fails, TripleDES will be attempted. If this is not available, it will try Blowfish. If this is also not available, the connection will be dropped. DES will not be attempted because most (new) servers don't support it due to its poor security.


For a list of all supported encryption methods, please refer to the EncryptionsEnum page. Additional encryption methods can be added to wodSSHTunnel on your request. If you have a requirement, please feel free to send your request to general@weonlydo.com.

Warning: changing this property also internally changes EncryptionList property.
