amazon-web-services - AWS CLI : Key is not in valid OpenSSH public key format

Question

如何解决这个问题？

# I used this command to create the key with a password
$ ssh-keygen -b 2048 -t rsa -C "awsfrankfurt" -f ~/.ssh/awsfrankfurt

# Then when I try to import it into AWS EC2, the error appears:
$ aws --region eu-central-1 ec2 import-key-pair \
    --key-name "awsfrankfurt" \
    --public-key-material ~/.ssh/awsfrankfurt

An error occurred (InvalidKey.Format) when the ImportKeyPair operation: 
Key is not in valid OpenSSH public key format

Answer 1

AWS 仅支持 RSA key 对，不支持 DSA , ECDSA或 Ed25519 key 对。如果您尝试上传非 RSA公钥你会得到这个错误。

这是记录在案 here :

Amazon EC2 does not accept DSA keys. Make sure your key generator is set up to create RSA keys.

该错误消息具有误导性，因为您可以上传有效的非 RSA键并得到错误:

Error import KeyPair: InvalidKey.Format: Key is not in valid OpenSSH public key format

对于在搜索此错误消息后找到此页面的人，此答案应该很有用。
