Hello everyone! I have googled this error to no avail, but all answers don’t seem to adjust to my particular case, or maybe I’m too novice at figuring it out. I have this key file: -----BEGIN OPENSSH PRIVATE KEY—— [key here] -----END OPENSSH PRIVATE KEY—— I’m trying to use this key in order to log in to my Google cloud instance through browser console, and I get the following error: "Error: Failed to read key. The key file must be ECDSA or RSA in PEM format. " I googled how to achieve this, and tried the following on my local machine: $ openssl rsa -in id_rsa.txt -out id_rsa.pem -outform PEM Sadly, I run into this error: unable to load Private Key 56081:error:0906D06C:PEM routines:PEM_read_bio:no start line:/BuildRoot/Library/Caches/com.apple.xbs/Sources/OpenSSL098/OpenSSL098-59.60.2/src/crypto/pem/pem_lib.c:648:Expecting: ANY PRIVATE KEY As I said, Google did throw some clues, but nothing conclusive. Note: I am running OS X El Cap. Can anyone point out what am I doing wrong? Thanks a lot in advance and I wish you a really good week!
