WinSCP 5.7.7 is over 5 years old. Please, do not use it!
We do not support old versions of WinSCP. Though I'm sure it does not support many of the algorithms listed.

Please, use the latest version of WinSCP.
It supports almost all the listed algorithms

The only missing is hmac-sha2-512, which depends on this PuTTY wish:

(and I believe that hmac-sha2-256 and hmac-sha256 is the same thing).

Hi Team,

Is there a document that lists which ciphers are supported by the versions of WinSCP 5.7.7? Also please let me know if the attached ciphers are supported by WinSCP 5.7.7 versions.

Thanks,
Priyanshu
