Could not load type 'System.Security.Cryptography.HMACRIPEMD160' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Hi,

We were trying to use the library on Ubuntu and when we try to establish a new session to an SFTP server we get the following error:

Could not load type 'System.Security.Cryptography.HMACRIPEMD160' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

So it must have an issue loading the SSH.NET library under the hood somewhere I would think. Has anyone run into this before? Do we need to recompile the library against .Net core.

Thanks in advance for any pointers.

Which version? The Betas are the only ones Im testing support for .Net Core that would run in Linux

I saw the same issue raised earlier https://github.com/darkoperator/Posh-SSH/issues/217 and at the time Powershell Core was not supported. It seems to indicate to support Powershell 7.0 now, so just wanted to confirm whether it should work on Core or not. Thanks

We are using 2.3.0 not the beta release. Powershell 7.1.3 and Posh 2.3.0

[darkoperator]

Only the beta versions should work on linux, that version is Windows only

Ok. We'll give the betas a try. Thank you.

We did test 3.0 beta and it works on Linux. I do have one question. There serve serveral cmdLet names in 2.x that ended in file, such as Get-SFTPFile. There is also a more generic Get-SFTPItem which exists in both 2.x and 3.0. Will the Get-SFTPFile cmdLets be re-added to 3.0 or should we start updating our code to use the more generic names. Thanks

Release notes say the cmdLets were removed, so I guess they won't be in 3.0. Should have checked notes before posting.

No problem, so to be clear, so I can replicate:

• the error happens in PS 7 on Windows and Linux
• happens on SFTP on all versions of Linux or only on unsupported old ones? (Need to check if I can get and ISO to build a VM)

Hi,

The assembly load error is gone. We only tested it on Linux as this is the only place we are using version 7.x. So we no longer have the original issue. We just noted that a few cmdLets had been removed in that version and that was already noted in the release notes. Since version 2.x also supports the Verb-SFTPItem cmdLets we can just update our code and not reference the Verb-SFTPFile cmdLets. I assume they were the same in 2.x and just had two names for the same thing.

Yep I left them in 2 introduced the new ones and in the redme and changelog before the change in 3 when I release it
