-<p>Using pseudorandom number generators (PRNGs) is security-sensitive. For example, it has led in the past to the following vulnerabilities:</p>
+<p>PRNGs are algorithms that produce sequences of numbers that only approximate true randomness. While they are suitable for applications like
+simulations or modeling, they are not appropriate for security-sensitive contexts because their outputs can be predictable if the internal state is
+known.</p>
+<p>In contrast, cryptographically secure pseudorandom number generators (CSPRNGs) are designed to be secure against prediction attacks. CSPRNGs use
+cryptographic algorithms to ensure that the generated sequences are not only random but also unpredictable, even if part of the sequence or the
+internal state becomes known. This unpredictability is crucial for security-related tasks such as generating encryption keys, tokens, or any other
+values that must remain confidential and resistant to guessing attacks.</p>
+<p>For example, the use of non-cryptographic PRNGs has led to vulnerabilities such as:</p>
