+.BI "\-A, \-\-seedalg " seed-alg
+Use the deterministic random number generator algorithm
+.I seed-alg
+to generate the key. Use
+.I before
+the
+.B \-s
+or
+.B \-n
+options; without one of these,
+.B \-A
+has no effect. The default algorithm is
+.BR rmd160-mgf .
+The command
+.B key show seed
+shows a list of recognized seeding algorithms. The seeding algorithm
+used to generate a key is recorded as the key's
+.B seedalg
+attribute.
+.TP
+.BI "\-s, \-\-seed " seed
+Generate the key deterministically using the given
+.IR seed ,
+which should be a Base64-encoded binary string. This is mainly useful
+for parameters keys (types
+.BR dsa-param
+and
+.BR dh-param ),
+to demonstrate that a set of parameters has been generated in an honest
+fashion. The
+.B dsarand
+generation algorithm can be used to generate
+.B dsa-param
+keys as required by FIPS186. The requested seed is recorded,
+Base64-encoded, as the new key's
+.B seed
+attribute.
+.TP
+.BI "\-n, \-\-newseed " bits
+Generate a new seed, with the given length in
+.IR bits .
+The generated seed is recorded, Base64-encoded, as the new key's
+.B seed
+attribute.
