 =head1 NAME
 
-DSA_size - Get DSA signature size
+DSA_size, DSA_bits - get DSA signature size or key bits
 
 =head1 SYNOPSIS
 
  #include <openssl/dsa.h>
 
- int DSA_size(DSA *dsa);
+ int DSA_size(const DSA *dsa);
+ int DSA_bits(const DSA *dsa);
 
 =head1 DESCRIPTION
 
-This function returns the size of an ASN.1 encoded DSA signature in
-bytes. It can be used to determine how much memory must be allocated
-for a DSA signature.
+DSA_size() returns the maximum size of an ASN.1 encoded DSA signature
+for key B<dsa> in bytes. It can be used to determine how much memory must
+be allocated for a DSA signature.
 
 B<dsa-E<gt>q> must not be B<NULL>.
 
+DSA_bits() returns the number of bits in key B<dsa>: this is the number
+of bits in the B<p> parameter.
+
 =head1 RETURN VALUE
 
-The size in bytes.
+DSA_size() returns the size in bytes.
+
+DSA_bits() returns the number of bits in the key.
