comment Program to generate a secure 128 bit key on a windows machine
Why use PSK suites? They're lacking basic security features like forward secrecy.

@user93353 Depends on what you want to achieve. Of course no unkeyed hash is a MAC.

comment Why is HMAC-SHA1 still considered secure?
@user93353 Like I said, the security of HMAC-SHA1 depends on the unknown key. If there is no key or it is known to the attacker, the collisions in SHA1 become a threat. But SHA1 should rarely be used in designs, since there are better alternatives available.

Should we close this as a duplicate of Is HMAC-MD5 considered secure for authenticating encrypted data?? While this question is about SHA1, not MD5, the answer is nearly the same.

Salsa20 is relatively common as well, due to its use in NaCl and its derivatives.
