无法确定DKIM密钥长度

Question

我创建了一个运行ssh-keygen -t rsa -b 4096的公钥和私钥。

我然后创建TXT类型与该值的DNS条目dkim._domainkey：

v=dkim1; p=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 

现在，当我测试用https://protodave.com/tools/dkim-key-checker/它说：

Unable to properly parse the public key string and determine key length or the key is invalid. Tip: Make sure there aren't any special charaters or newlines pasted into your key in the TXT record. 

我只是复制粘贴的完整键出由ssh-keygen生成的文件。有关如何找出问题的任何提示？

Answer 1

我用openssl genrsa -out openssl.priv 1024和openssl rsa -in openssl.priv -pubout >openssl.pub生成密钥，现在它工作得很好。
