+.SH "DESCRIPTION"
+.PP
+The Signature Verification Tool,
+\fBsignver\fR, is a simple command\-line utility that unpacks a base\-64\-encoded PKCS#7 signed object and verifies the digital signature using standard cryptographic techniques\&. The Signature Verification Tool can also display the contents of the signed object\&.
+.SH "OPTIONS"

+\fBsignver\fR

+key3\&.db, and
+secmod\&.db) and new SQLite databases (cert9\&.db,
+key4\&.db, and
+pkcs11\&.txt)\&. If the prefix
+\fBdbm:\fR

+.SH "NSS DATABASE TYPES"
+.PP
+NSS originally used BerkeleyDB databases to store security information\&. The last versions of these
+\fIlegacy\fR
+databases are:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1

+.\}
+.el \{\

+secmod\&.db for PKCS #11 module information
+.RE
+.PP
+BerkeleyDB has performance limitations, though, which prevent it from being easily used by multiple applications simultaneously\&. NSS has some flexibility that allows applications to use their own, independent database engine while keeping a shared database and working around the access issues\&. Still, NSS requires more flexibility to provide a truly shared security database\&.
+.PP
+In 2009, NSS introduced a new set of databases that are SQLite databases rather than BerkleyDB\&. These new databases provide more accessibility and performance:
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+cert9\&.db for certificates
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+key4\&.db for keys
+.RE
+.sp
+.RS 4
+.ie n \{\
+\h'-04'\(bu\h'+03'\c
+.\}
+.el \{\
+.sp -1
+.IP \(bu 2.3
+.\}
+pkcs11\&.txt, which is listing of all of the PKCS #11 modules contained in a new subdirectory in the security databases directory
+.RE
+.PP
+Because the SQLite databases are designed to be shared, these are the
+\fIshared\fR
+database type\&. The shared database type is preferred; the legacy format is included for backward compatibility\&.
+.PP
+By default, the tools (\fBcertutil\fR,
+\fBpk12util\fR,
+\fBmodutil\fR) assume that the given security databases use the SQLite type Using the legacy databases must be manually specified by using the
+\fBdbm:\fR
+prefix with the given security directory\&. For example:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+# signver \-A \-s \fIsignature\fR \-d dbm:/home/my/sharednssdb
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+To set the legacy database type as the default type for the tools, set the
+\fBNSS_DEFAULT_DB_TYPE\fR
+environment variable to
+\fBdbm\fR:
+.sp
+.if n \{\
+.RS 4
+.\}
+.nf
+export NSS_DEFAULT_DB_TYPE="dbm"
+.fi
+.if n \{\
+.RE
+.\}
+.PP
+This line can be added to the
+~/\&.bashrc
+file to make the change permanent for the user\&.
