They should be of the form:\n\nssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAwVa6M6cGVmUcLl2cFzkxEoJd06Ub4bVDsYrWvXhvUV+ZAM9uGuewZBDoAqNKJxoIn0Hyd0Nk/yU99UVv6NWV/5YSHtnf35LKds56j7cuzoQpFIdjNwdxAN0PCET/MG8qyskG/2IE2DPNIaJ3Wy+Ws4IZEgdJgPlTYUBWWtCWOGc= someone@hostname\n\nYou must make sure that ~/.ssh, and the key file, are only writable by the\nuser. Beware of editors that split the key into multiple lines.\n\nDropbear supports some options for authorized_keys entries, see the manpage.\n\n============================================================================\n\nClient public key auth:\n\nDropbear can do public key auth as a client, but you will have to convert\nOpenSSH style keys to Dropbear format, or use dropbearkey to create them.\n\nIf you have an OpenSSH-style private key ~/.ssh/id_rsa, you need to do:\n\ndropbearconvert openssh dropbear ~/.ssh/id_rsa  ~/.ssh/id_rsa.db\ndbclient -i ~/.ssh/id_rsa.db \u003chostname\u003e\n\nDropbear does not support encrypted hostkeys though can connect to ssh-agent.\n\n============================================================================\n\nIf you want to get the public-key portion of a Dropbear private key, look at\ndropbearkey's '-y' option.\n\n============================================================================\n\nTo run the server, you need to server keys, this is one-off:\n./dropbearkey -t rsa -f dropbear_rsa_host_key\n./dropbearkey -t dss -f dropbear_dss_host_key\n./dropbearkey -t ecdsa -f dropbear_ecdsa_host_key\n\nor alternatively convert OpenSSH keys to Dropbear:\n./dropbearconvert openssh dropbear /etc/ssh/ssh_host_dsa_key dropbear_dss_host_key\n\nYou can also get Dropbear to create keys when the first connection is made -\nthis is preferable to generating keys when the system boots. Make sure \n/etc/dropbear/ exists and then pass '-R' to the dropbear server.\n\n============================================================================\n\nIf the server is run as non-root, you most likely won't be able to allocate a\npty, and you cannot login as any user other than that running the daemon\n(obviously). Shadow passwords will also be unusable as non-root.\n\n============================================================================\n\nThe Dropbear distribution includes a standalone version of OpenSSH's scp\nprogram. You can compile it with \"make scp\", you may want to change the path\nof the ssh binary, specified by _PATH_SSH_PROGRAM in options.h . By default\nthe progress meter isn't compiled in to save space, you can enable it by \nadding 'SCPPROGRESS=1' to the make commandline.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Forc%2Fdropbear","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Forc%2Fdropbear","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Forc%2Fdropbear/lists"}
