<p>Hashing algorithms vary in complexity, security, and length of output. Here are some of the most widely used types:</p> | ||
<h6 id="md5-message-digest-algorithm-5">MD5 (Message Digest Algorithm 5)<a class="headerlink" href="#md5-message-digest-algorithm-5" title="Permanent link">¶</a></h6> | ||
<ul> | ||
<li>Produces a 128-bit hash.</li> | ||
<li>It’s fast but vulnerable to collisions, meaning two different inputs can produce the same hash. Due to these vulnerabilities, MD5 is generally not recommended for secure applications today.</li> | ||
</ul> | ||
<h6 id="sha-1-secure-hash-algorithm-1">SHA-1 (Secure Hash Algorithm 1)<a class="headerlink" href="#sha-1-secure-hash-algorithm-1" title="Permanent link">¶</a></h6> | ||
<ul> | ||
<li>Produces a 160-bit hash.</li> | ||
<li>SHA-1 was widely used in the past but is now considered insecure for most applications due to susceptibility to collision attacks.</li> | ||
</ul> | ||
<h6 id="sha-2-secure-hash-algorithm-2">SHA-2 (Secure Hash Algorithm 2)<a class="headerlink" href="#sha-2-secure-hash-algorithm-2" title="Permanent link">¶</a></h6> | ||
<ul> | ||
<li>A family of hash functions that includes SHA-256 (producing a 256-bit hash) and SHA-512 (producing a 512-bit hash).</li> | ||
<li>SHA-256 is a highly secure and widely used hashing algorithm, particularly in cryptocurrency and digital certificates.</li> | ||
</ul> | ||
<h6 id="sha-3-secure-hash-algorithm-3">SHA-3 (Secure Hash Algorithm 3)<a class="headerlink" href="#sha-3-secure-hash-algorithm-3" title="Permanent link">¶</a></h6> | ||
<ul> | ||
<li>A newer standard designed to offer security even against advanced attacks. It’s computationally intensive but highly secure, often used in cryptographic applications that require maximum security.</li> | ||
</ul> | ||
<p>Each of these algorithms are designed with specific trade-offs in mind between security, performance, and output size.</p> | ||
