Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added '192.168.1.4' (ECDSA) to the list of known hosts When you install the openssh-server package, it automatically generates keys for the server to use. That is where the keys with the unknown fingerprint came from. If you want to see the fingerprint of the SSH server's (RSA*) key, you could run ssh-keygen -lf /etc/ssh/ssh_host_rsa_key.pub. *There are different encryption algorithms If you do not have another instance, whose fingerprints you know, create new temporary instance, just for the purpose of collecting the keys. First find keys for the new temporary instance, using it's initial start log. Connect to the temporary instance from public network. Then collect keys of the target instance by connecting to it from the temporary instance, over private Amazon network. After that you can discard the temporary instance ec2-fingerprint-key .ssh/key.pem (path to your private key / key name) , this will show you the fingerprint of your desktop private key which you can then compare to the public one shown in the web-based management console, under key pairs. They should match but it is not very convincing as a solution

If you've ever connected to a new server via SSH, you were probably greeted with a message about how the authenticity of the host couldn't be established. The message and prompt looks something like this: The authenticity of host '1.2.3.4 (1.2.3.4)' can't be established.

Host key verification failed This is also why ECDSA can be slower than RSA for signing and verification. Rather than a few operations on extremely large numbers, it's many operations on smaller numbers. Maths & Implementations. That was probably a bad explanation. It probably didn't convey nuance as deserved. The best resource that I could find to explain how to get the Public Key from the Private key was this: https. Once you connect to a remote system its fingerprint is saved to the known_hosts file. Every subsequent time you connect to that machine, SSH checks the fingerprint against the known_hosts file to verify it's identity. When using SSH in an automated fashion, such as shell scripting, this can be a show stopper. However, there are several. Now, with some online tools, this SHA256 fingerprint can be converted from base64 to hex, which then compares to the SSHFP records. ;) Uff. That is: The the ECDSA fingerprint in SHA-256 in the hex variant (beginning with 4f:4f:7f as seen in the SSHFP type 3 2 record) is the correct one as in the base64 variant (beginning with T09/)

To verify a fingerprint you need to know the correct one first. These to-be-verified correct fingerprints can be shown after you're logged in on the target server. Of course this is a classic chicken-and-egg problem. You need to get the correct fingerprints through an independent communication channel in beforehand. In our case that is the list. Open the file known_hosts with a text editor and remove the line with your device's host name or IP-address and the ecdsa key hint (e.g. ecdsa-sha2-nistp25). Open Terminal and enter nano ~/.ssh/known_hosts. Move the cursor to the respective line and hit ctrlK to remove the line. To save the modified file and exit nano hit ctrlO and ctrlX. The known_hosts file looks like this: ip-address (or. Fingerprint Variations. Host key fingerprints are host and protocol specific. Regardless of which SSH client you use to access the host, the key fingerprint should always exactly match a fingerprint listed in this document for the host and protocol you are accessing. Confirming Bad Key Dat

The fingerprint is calculated using a hash function such as SHA-256, SHA-1, or MD5. Due to weaknesses in SHA-1 and MD5, the type of fingerprint which is now most recommended is SHA-256. The client might not be configured with a host key, or might expect a different host key than is received from the server. In this case, a secure client must either prevent the connection, or require the user. ECDSA key fingerprint is aa:bb:1f:cc:f1:ab:7c:71:9b:62:37:8c:f1:60:2e:98.

Are you sure [ When you originally log into a DreamHost server, you may see the following warning: The server's host key is unknown. You have no guarantee that the server is the computer you think it is. For example: To confirm if this is the correct server, navigate to the SSH Keys page. On that page, you'll see your server along with its matching Fingerprints The first time a user connects to your SSH/SFTP server, he'll be presented with your server's fingerprint. To verify, the user can contact you and you can then dictate to him your record of the fingerprint. If they match, the user can then store that fingerprint for future sessions. Most SSH/SFTP clients allow users to save fingerprints I'm having trouble with setting up my Windows Hello - everything is ok, but when I try to add my fingerprint, i've got message that my fingerprint is allready in use (That fingerprint has already been set up on another account. Try a different finger.) I've tried MANY things to solve that (device driver reinstall, bios memory cleaning, enabling/disabling PIN). Where do Windows keeps that.
