文字超出 fbox 范围

我有以下一段 Latex 代码。我希望文本位于该框内，但它却在框外。有人可以帮忙吗？

\documentclass[]{article}
\usepackage{varwidth}

\usepackage{refcount}
\usepackage[colorlinks]{hyperref}
\makeatletter
\setlength{\@fptop}{0pt}
\makeatother
\usepackage [
  n,
  advantage,
  operators,
  sets,
  adversary,
  landau,
  probability,
  notions,
  logic,
  ff,
  mm,
  primitives,
  events,
  complexity,
  asymptotics,
  keys
] {cryptocode}
\usepackage{cryptocode}
\usepackage{changepage}
    \begin{figure}
    
    \fbox{\begin{minipage}{\dimexpr\textwidth-2\fboxsep-2\fboxrule\relax}
    \procedure[linenumbering]{${\bf Exp}_{{\sf IB-MSS}}^{uf-cma}(\adv)$}{%
      ({\sf pp},MSK) \gets {\sf Setup}(\eta); {\sf MIdLst}\gets \emptyset ; {\sf CIdLst} \gets \emptyset   \\
      \text{Run } \adv({\sf pp}), \text{and handle } \adv \text{’s key derivation and signature queries as follows:}  \\
      \text{On a key derivation query on identity ${\sf Id}$, add ${\sf Id}$ to ${\sf CIdLst}$, run ${\sf KeyGen}$ on input $(MSK, {\sf Id})$ and return ${\sf sk_{Id}}$ to $\adv$}\\
    \text{On a signing query on pair $({\sf msg, Id})$, add ${\sf (msg, Id)}$ to ${\sf MIdLst}$}\\
     \text{run ${\sf Sign}$ protocol on behalf of identity ${\sf Id}$ on message ${\sf msg}$ forwarding messages to and from $\adv$.}\\
     \text{When $\adv$ halts, parse its output as ${\sf (msg}, IdSet, \sigma)$} \\ 
     \text{If ${\sf Verify}({\sf pp, msg},IdSet, \sigma )=1 \wedge (\exists;\ {\sf Id}\in IdSet$  such that $({\sf Id}\notin {\sf CIdLst}) \wedge (({\sf msg, Id})\notin {\sf MIdLst})) $ then return $1$, otherwise return $0$.}
      }\end{minipage}}
    
    \end{figure}

问题在于数学模式不会自动添加换行符。在数学模式下使用加密代码时，一种选择是使用手动换行符，可能与\pcskipln以下方法一起使用

\procedure[linenumbering]{Header}{%
  \text{first line}   \\
  \text{some long}  \pcskipln\\
  \text{line} \\
  \text{some long}  \pcskipln\\
  \text{line} 
}

这会产生类似下列的结果。

手动换行示例

由于您的情况与文本相比，数学部分实际上很小，因此我建议在文本模式下使用加密代码，mode=text并使用选项width。以下是调整为 8cm 宽度的示例。

\documentclass[]{article}
\usepackage{varwidth}

\usepackage{refcount}
\usepackage[colorlinks]{hyperref}
\makeatletter
\setlength{\@fptop}{0pt}
\makeatother
\usepackage [
  n,
  advantage,
  operators,
  sets,
  adversary,
  landau,
  probability,
  notions,
  logic,
  ff,
  mm,
  primitives,
  events,
  complexity,
  asymptotics,
  keys
] {cryptocode}
\usepackage{cryptocode}
\usepackage{changepage}

\begin{document}

\begin{figure}
   
 \begin{pchstack}[center]
    \fbox{\procedure[linenumbering,width=8cm,mode=text]{${\bf Exp}_{{\sf IB-MSS}}^{uf-cma}(\adv)$}{%
      $({\sf pp},MSK) \gets {\sf Setup}(\eta); {\sf MIdLst}\gets \emptyset ; {\sf CIdLst} \gets \emptyset$   \\
      Run $\adv({\sf pp})$, and handle $\adv$’s key derivation and signature queries as follows:  \\
      On a key derivation query on identity ${\sf Id}$, add ${\sf Id}$ to ${\sf CIdLst}$, run ${\sf KeyGen}$ on input $(MSK, {\sf Id})$ and return ${\sf sk_{Id}}$ to $\adv$\\
    On a signing query on pair $({\sf msg, Id})$, add ${\sf (msg, Id)}$ to ${\sf MIdLst}$\\
     run ${\sf Sign}$ protocol on behalf of identity ${\sf Id}$ on message ${\sf msg}$ forwarding messages to and from $\adv$.\\
     When $\adv$ halts, parse its output as ${\sf (msg}, IdSet, \sigma)$ \\ 
     If ${\sf Verify}({\sf pp, msg},IdSet, \sigma )=1 \wedge (\exists;\ {\sf Id}\in IdSet$  such that $({\sf Id}\notin {\sf CIdLst}) \wedge (({\sf msg, Id})\notin {\sf MIdLst})) $ then return $1$, otherwise return $0$.
      }}
      \end{pchstack}
\end{figure}
        
\end{document}

得出的结果为：

附注：您可能需要查看\createprocedureblock为居中和框式伪代码部分创建便捷命令。
