Ssh-keygen public key format

Public key: there are two public key formats, standard format and one-line format

-- END SSH2 PUBLIC KEY--

One-line format

This format is required for Openssh servers. Copy the public key into the authorized_keys file. The format in which the public key generated by PuTTYgen is copied and pasted into the SSH server is the one-line format.

For example, ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAwtUKdm+wzgBIJPazvE3v2DXrFSMiOxv/ch+hR7aqq2pw7Hk6+r7Mpsic4+22ZNC91HjqlBEfsoQ+/rz + e8qcJM17s8SNeumysWOBxFY913SXG5gDpyWMwQhISCPflcudPjImz5ytRYQZroomYtW4QHz54h6Clw18x9qidOQfPESuFc = rsa-key-20101208

After all of the above, the crux of the problem boils down to the conversion of several formats:

1. IETF SECSH-> OpenSSH

Use OpenSSH's ssh-keygen: $ssh-keygen-I-f privatekey > newprivatekey

2. OpenSSH-- > IETF SECSH

Use OpenSSH's ssh-keygen: $ssh-keygen-e-f privatekey > newprivatekey

Use ssh3's ssh-keygen2: $ssh-keygen-x privatekey

3. Conversion of PuTTY format:

Use puttygen.exe

3.1 other two formats-> PuTTY format

In addition to Load private keys in its own format (.ppk), private keys in other formats can be directly Load, and can be automatically identified and converted into keys in PuTTY format, such as OpenSSH private keys.

3.2 you can also use PuTTY format-> the other two formats
