用OpenSSH的人都知ssh会把你每个你访问过计算机的公钥(public key)都记录在~/.ssh/known_hosts。当下次访问相同计算机时,OpenSSH会核对公钥。如果公钥不同,OpenSSH会发出警告,避免你受到DNSHijack之类的攻击。 SSH对主机的public_key的检查等级是根据StrictHostKeyChecking变量来配置的。默认情况下,StrictHostKeyCheckin...
debug1: send_pubkey_test: no mutual signature algorithmPermission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.A possible resolution for this issue is to create the key using ED25519 instead: ...
For keyboard interactive authentication it is also possible to restrict authentication to a specific device by appending a colon followed by the device identifierbsdauth,pam, orskey, depending on the server configuration. For example, “keyboard-interactive:bsdauth” would restrict keyboard interactive a...
If you don't specify an algorithm, Ed25519 is used. A strong algorithm and key length should be used, such as ECDSA in this example. To generate key files by using the ECDSA algorithm, run the following command in a PowerShell or Command Prompt window on your client: ...
algorithm Specifies the algorithm(s) to be used as a single string of comma-separated variables (no spaces) in priority order from those shown below: blowfish-cbc– symmetric-key block cipher, Cipher Block Chaining, CBC 3des-cbc– Triple Data Encryption Standard, CBC...
To generate key files using the RSA algorithm supported by Azure DevOps (either RSA-SHA2-256 or RSA-SHA2-512), run one of the following commands from a PowerShell or another shell such asbashon your client: PowerShell ssh-keygen-trsa-sha2-256 ...
