<p>The flag to enable checksumming of Berkeley DB databases pages was renamed
from DB_CHKSUM_SHA1 to <a href="../api_reference/C/dbset_flags.html#dbset_flags_DB_CHKSUM" class="olink">DB_CHKSUM</a>, as Berkeley DB uses an internal
function to generate hash values for unencrypted database pages, not
the SHA1 Secure Hash Algorithm. Berkeley DB continues to use the SHA1 Secure
Hash Algorithm to generate hashes for encrypted database pages.
Applications using the DB_CHKSUM_SHA1 flag should change that use to
<a href="../api_reference/C/dbset_flags.html#dbset_flags_DB_CHKSUM" class="olink">DB_CHKSUM</a>; no other change is required.</p>
