Quoting from the docs for Define IPSec Crypto Profiles, it says
For the authentication algorithm, use SHA-256 or higher (SHA-384 or higher preferred for long-lived transactions). Do not use SHA-512, SHA-1, or MD5.
Whereas, going from most to least secure, it recommends the below order
Authentication—sha512, sha384, sha256, sha1, md5.
Can someone please help clarify what is right or wrong ? Thanks!

@devd_25 Anything from SHA256 and above is secure. To use SHA-512 or SHA-384, you need to have compatible servers and are not widely used. Other reasons include processing time. Following public links can add some more info
Hi @BatD , thats right. However, if you notice, first it says
Do not use SHA-512, SHA-1, or MD5.
Then, it recommends in the order of most to least secure starting with SHA-512, implying that SHA-512 is most secure. Hence, needed clarification on that. Might be a documentation error.
