<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>
