SSHCompressionAlgorithms Property

A comma-separated list containing all allowable compression algorithms.

Syntax

ANSI (Cross Platform)
char* GetSSHCompressionAlgorithms();
int SetSSHCompressionAlgorithms(const char* lpszSSHCompressionAlgorithms); Unicode (Windows) LPWSTR GetSSHCompressionAlgorithms();
INT SetSSHCompressionAlgorithms(LPCWSTR lpszSSHCompressionAlgorithms);
@property (nonatomic,readwrite,assign,getter=SSHCompressionAlgorithms,setter=setSSHCompressionAlgorithms:) NSString* SSHCompressionAlgorithms;
- (NSString*)SSHCompressionAlgorithms;
- (void)setSSHCompressionAlgorithms:(NSString*)newSSHCompressionAlgorithms;
#define PID_SFTP_SSHCOMPRESSIONALGORITHMS 45

IPWORKSSFTP_EXTERNAL void* IPWORKSSFTP_CALL IPWorksSFTP_SFTP_Get(void *lpObj, int propid, int arridx, int *lpcbVal, int64 *lpllVal);
IPWORKSSFTP_EXTERNAL int IPWORKSSFTP_CALL IPWorksSFTP_SFTP_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

"none,zlib"

Remarks

During the SSH handshake, this list will be used to negotiate the compression algorithm to be used between the client and server. This list is used for both directions: client to server and server to client. When negotiating algorithms, each side sends a list of all algorithms it supports or allows. The algorithm chosen for each direction is the first algorithm to appear in the sender's list that the receiver supports, so it is important to list multiple algorithms in preferential order. If no algorithm can be agreed upon, the class will raise an error and the connection will be aborted.

At least one supported algorithm must appear in this list. The following compression algorithms are supported by the class:

  • zlib
  • zlib@openssh.com
  • none
