I recently opened a feature request in the bugzilla [0], and was wondering if anyone has any opinions about it. [0] https://bugzilla.mindrot.org/show_bug.cgi?id=3849 The full text of the bug: Currently ssh and ssh-keygen don't manage to read private keys that don't have a newline at the end. It fails with this error: ``` openssh-portable/$ ./ssh-keygen -y -f no_newline_ed25519 Load key "no_newline_ed25519": error in libcrypto ``` Adding a newline to the end fixes it: ``` openssh-portable/$ echo $'\n' >> no_newline_ed25519 openssh-portable/$ ./ssh-keygen -y -f no_newline_ed25519 ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIImNVUrqnrw2eKhwaX1bGpNu3isBRESXny4NF9gjnHRi comment ``` Earlier versions failed with an `invalid format` error. I suggest not checking if there is a new line (\n) at the end of the private key. This matches the behavior of openssl, and in general makes it more user friendly. A lot of text editors don't show if there is a newline at the end of the file, and private keys are often copied and pasted. See some examples for people having trouble with this behaviour: [1][2][3][4]
