<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>PKCS12_decrypt_skey() Decrypt the PKCS#8 shrouded keybag contained within <i>bag</i> using the supplied password <i>pass</i> of length <i>passlen</i>.</p>

<p>PKCS12_decrypt_skey_ex() is similar to the above but allows for a library context <i>ctx</i> and property query <i>propq</i> to be used to select algorithm implementations.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>Both functions will return the decrypted key or NULL if an error occurred.</p>
