Thank you for that, I imported into Excel as a class module, and tried to call the function sha256, which shows #REF ?

ah, so you're using it in a formula. Add this to a regular module:<br />

<pre><code id="code-20-39779813-1">Public Function SHA256Hash(strInput As String)
    Dim oSHA256 As CSHA256
    Set oSHA256 = New CSHA256

    SHA256Hash = oSHA256.SHA256(strInput)

    Set oSHA256 = Nothing
End Function</code></pre>
<br />
In a formula:<br />

<pre><code id="code-20-39779813-2">=SHA256Hash(&quot;Test&quot;)</code></pre>
or<br />

<pre><code id="code-20-39779813-3">=SHA256Hash(A1)</code></pre>
</div>

In a formula:


=SHA256Hash("Test")

or


=SHA256Hash(A1)

Hi,<br />
<br />
I need to protect a sheet of passwords using SHA-256 Hashing, I have working macro scripts for MD5 and SHA-1, I would like to implement SHA-256 but can not find any macro code to achieve this.
