- * XXX Want to have a SGN_DecodeDigestInfo, like:
- *	SGNDigestInfo *SGN_DecodeDigestInfo(SECItem *didata);
- * that creates a pool and allocates from it and decodes didata into
- * the newly allocated DigestInfo structure.  Then fix secvfy.c (it
- * will no longer need an arena itself) to call this and then call
- * DestroyDigestInfo when it is done, then can remove the old template
- * above and keep our new template static and "hidden".
