I have problems to make the below formula look great. Do you have any ideas on how I can make it look better?

This is this LaTeX code I have for it:

PTK = $PRF(PMK, text{"Pairwise key expansion"} || Min(AA, SPA) || \ Max{AA, SPA}|| Min(ANonce, SNonce) ||  Max(ANonce,SNonce))$

I appreciate all help!

I don't know if it looks great, but do you want something like this?

documentclass{article}

usepackage{amsmath}



begin{document}



[

begin{split}

text{PTK} = & text{PRF}left( text{PMK}, text{"Pairwise key expansion"} || min(text{AA}, text{SPA}) || right. \ 

& left. qquad max(text{AA}, text{SPA})|| min(text{ANonce}, text{SNonce}) ||  max(text{ANonce},text{SNonce})right)

end{split}

]



end{document}

Taking Ignasi's approach a step further...

documentclass{article}

usepackage{amsmath}

begin{document}

[

begin{split}

text{PTK} =  text{PRF}bigl( &text{PMK}, text{``Pairwise key expansion''} \& || min(text{AA}, text{SPA})  \ 

& || max(text{AA}, text{SPA})\&|| min(text{ANonce}, text{SNonce}) \&||  max(text{ANonce},text{SNonce})bigr)

end{split}

]

end{document}

IMHO your formula is in an algorithm and || stands for "or". So you should have a look at algorithm packages. Anyway this is a non-algorithm but algorithmic answer:

documentclass{article}

usepackage{amsmath}

begin{document}

[

begin{array}{r@{}l@{}l}

    text{PTK}=PRF&(PMK, & text{``Pairwise key expansion''}\

    && || min(AA,SPA)\

    && || max(AA,SPA)\

    && || min(ANonce,SNonce)\

    && || max(ANonce,SNonce)\

    &)&

end{array}

]

end{document}

Edit 1: Improved version

I prefer this way.

documentclass{article}

usepackage{amsmath}

begin{document}

[

begin{array}{rl}

    text{PTK}=PRF(&\

    & PMK,\

    & (\

    & quadtext{``Pairwise key expansion''}\

    & quad||min(AA,SPA)\

    & quad||max(AA,SPA)\

    & quad||min(ANonce,SNonce)\

    & quad||max(ANonce,SNonce)\

    & )\

    )&

end{array}

]

end{document}

I have two proposals. Most important is to properly define macros for specific object types in your document, in order to ensure uniformity.

documentclass{article}

usepackage{amsmath}



newcommand{OOR}{mathrel{|}}

newcommand{tvar}[1]{mathrm{#1}}

newcommand{tdesc}[1]{textup{``#1''}}



begin{document}



[

begin{aligned}

tvar{PTK}=tvar{PRF}bigl(

 &tvar{PMK},tdesc{Pairwise key expansion} \

 & OOR min(tvar{AA},tvar{SPA})\

 & OOR max(tvar{AA},tvar{SPA})\

 & OOR min(tvar{ANonce},tvar{SNonce})\

 & OOR max(tvar{ANonce},tvar{SNonce}) bigr)

end{aligned}

]



begin{multline*}

tvar{PTK}=tvar{PRF}bigl(

 tvar{PMK},tdesc{Pairwise key expansion}

 OOR min(tvar{AA},tvar{SPA}) OOR \

 max(tvar{AA},tvar{SPA})

 OOR min(tvar{ANonce},tvar{SNonce})

 OOR max(tvar{ANonce},tvar{SNonce}) bigr)

end{multline*}



end{document}
