I just tried to access my Raspebrry Pi using SFTP, by using my private key, however I am getting the below error
Is this because my key was generated with the ED25519 algorithm? If so, is there any chance for supporting this key type?
It could be due to that. Can you try using a different / more common algorithm to check?
It can also depend on which tool generated the key file, as there are some slightly different formats and it has to be the one that PuTTY uses. The PuttyGen tool can load most formats and convert them to the required one.
Hi Leo,
Yeah I just checked with an RSA 4096 key and it works with that one.
As an aside, I tried my ED25519 key with WinSCP and it accepts it (it must be converted to PPK format first, which I did...and is the key I tried with DOpus)
Currently supported algorithms are:
KEX: diffie-hellman-group-exchange-sha256, diffie-hellman-group-exchange-sha1, diffie-hellman-group14-sha1, diffie-hellman-group1-sha1, rsa2048-sha256, rsa1024-sha1
Cipher: Blowfish-256 SDCTR, Blowfish-128 CBC, single-DES CBC, triple-DES SDCTR, triple-DES SDCTR, triple-DES CBC, AES-256 SDCTR, AES-256 CBC, AES-192 SDCTR, AES-192 CBC, AES-128 SDCTR, AES-128 CBC, Arcfour-256, Arcfour-128
MAC: HMAC-SHA-256, HMAC-SHA1, HMAC-SHA1-96, HMAC-MD5
Hello Jon,
will there be Ed25519 public-key cryptography support? For the time being I can't use the Advanced FTP feature because of this.
Thanks in advance.
Kind regards,
David
Until support for ED25519 is considered for implementation, I'm guessing you will need to use another cryptography method that is supported, as @Jon has already mentioned.
As I said, I'm currently using it with RSA 4096 keys and it's working fine, and I'm pretty sure that would be adequate cryptography at least for my use case scenario.
I used ed25519 key-pair a few years, I can't belive dopus not support it, ed25519 work well in my tools such as putty/winscp/xshell/xftp, but it't not work in dopus, and I will not add a new rsa in each vps, I will not advice my friends or colleagues buy dopus if he use sftp.
Just got bit by this. Why after 2 years do we still not have it?
Oh, ... You Poor Thing .
Why do you need it within Directory Opus so urgently ?
