My AWS instance says it is configured to use the only keypair I have on my account and it has a fingerprint in the format of:



3c:64:a7:85:53:3f:81:1c:24:5a:d2:6a:5b:76:47:da:f3:14:63:88



I have a key.pem file on my computer. How do I verify that this pem file matches up with the above key-pair fingerprint provided by AWS?



I have attempted the following:
ssh-keygen -lf key.pem



That outputs something in this format:
2048 SHA256:TpL6i8y1uCd26IUVVc5UHFluP7GLKD/T3O1+K4Pc0qg no comment (RSA)



The encoding scheme is different, I am not able to tell if they are equivalent.



I am trying to debug why I am unable to ssh into my instance with this key, this is the first step I am trying.






amazon-web-services ssh-keygen

There are two methods, depending on how you created your SSH key as described in Verifying Your Key Pair's Fingerprint in AWS docs.



Here is my SSH key fingerprint in the console:



EC2 Key Pairs Screenshot



And here is how to get the same fingerprint from the command line:



~ $ openssl rsa -in ~/.ssh/aws-sandpit.pem -pubout -outform DER | openssl md5 -c
writing RSA key
(stdin)= ae:ae:56:84:f9:72:c4:d1:0a:b8:e9:3b:ab:d4:a7:00


If that doesn't match try this:



~ $ openssl pkcs8 -in path_to_private_key -inform PEM -outform DER -topk8 -nocrypt | openssl sha1 -c


Hope that helps :)

It is a team of 2: just I and my supervisor. Diurnally, I am posed with a "bug of the day" to get out of this C++ code. My supervisor generally gives me about 15-30 minutes to solve it and then accosts me about whether or not the task is completed and then rinses and repeats this until the end of the day.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of
