an example of sftp in golang

go_sftp.go

package main

import (
  "github.com/pkg/sftp"
  "golang.org/x/crypto/ssh"
)

func main() {
  addr := “my_ftp_server:22"
  config := &ssh.ClientConfig{
    User: “my_user",
    Auth: []ssh.AuthMethod{
      ssh.Password(“my_password"),
    },
    //Ciphers: []string{"3des-cbc", "aes256-cbc", "aes192-cbc", "aes128-cbc"},
  }
  conn, err := ssh.Dial("tcp", addr, config)
  if err != nil {
    panic("Failed to dial: " + err.Error())
  }
  client, err := sftp.NewClient(conn)
  if err != nil {
    panic("Failed to create client: " + err.Error())
  }
  // Close connection
  defer client.Close()
  cwd, err := client.Getwd()
  println("Current working directory:", cwd)
}

If you get this error message panic: ssh: handshake failed: ssh: no common algorithm for client to server cipher;, then add for instance "aes128-cbc" to supportedCiphers in $GOPATH/src/golang.org/x/crypto/ssh/common.go. More details in this issue.

No need to edit the package :-)

config := &ssh.ClientConfig{
User: “my_user",
Auth: []ssh.AuthMethod{
ssh.Password(“my_password"),
},
Config: ssh.Config{
Ciphers: []string{"aes128-cbc"},
}
},
