SSH Algorithms

WinSCP supports the following algorithms with SSH.

To see algorithms supported by your specific version of WinSCP, use /info command-line switch.

  • Encryption ciphers: aes256-ctr, aes256-cbc,, aes192-ctr, aes192-cbc, aes128-ctr, aes128-cbc,, blowfish-ctr, blowfish-cbc, 3des-ctr, 3des-cbc, arcfour256, arcfour128, des-cbc,


  • Compression formats: zlib,, none
