     d2i_DSAPublicKey() and i2d_DSAPublicKey() decode and encode
     the DSA public key components structure.

     d2i_DSA_PUBKEY() and i2d_DSA_PUBKEY() decode and encode an
     DSA public key using a SubjectPublicKeyInfo (certificate
     public key) structure.

     d2i_DSAPrivateKey(), i2d_DSAPrivateKey() decode and encode
     the DSA private key components.

     d2i_DSAparams(), i2d_DSAparams() decode and encode the DSA
     parameters using a DDDDssssssss---PPPaaaarrrrmmmmssss structure as defined in
     RFC2459.

     d2i_DSA_SIG(), i2d_DSA_SIG() decode and encode a DSA
     signature using a DDDDssssssss---SSSiiiigggg---VVVaaaalllluuuueeee structure as defined in
     RFC2459.

     The usage of all of these functions is similar to the
     d2i_X509() and i2d_X509() described in the d2i_X509(3)

     The DDDDSSSSAAAA structure passed to the private key encoding
     functions should have all the private key components
     present.

     The data encoded by the private key functions is unencrypted
     and therefore offers no private key security.

     The DDDDSSSSAAAA_PPPPUUUUBBBBKKKKEEEEYYYY functions should be used in preference to the
     DDDDSSSSAAAAPPPPuuuubbbblllliiiiccccKKKKeeeeyyyy functions when encoding public keys because
     they use a standard format.

     The DDDDSSSSAAAAPPPPuuuubbbblllliiiiccccKKKKeeeeyyyy functions use an non standard format the
     actual data encoded depends on the value of the wwwwrrrriiiitttteeee_ppppaaaarrrraaaammmmssss
     field of the aaaa key parameter.  If wwwwrrrriiiitttteeee_ppppaaaarrrraaaammmmssss is zero then
     only the ppppuuuubbbb_kkkkeeeeyyyy field is encoded as an IIIINNNNTTTTEEEEGGGGEEEERRRR. If
     wwwwrrrriiiitttteeee_ppppaaaarrrraaaammmmssss is 1 then a SSSSEEEEQQQQUUUUEEEENNNNCCCCEEEE consisting of the pppp, qqqq, gggg
     and ppppuuuubbbb_kkkkeeeeyyyy respectively fields are encoded.

     The DDDDSSSSAAAAPPPPrrrriiiivvvvaaaatttteeeeKKKKeeeeyyyy functions also use a non standard
     structure consiting consisting of a SEQUENCE containing the
     pppp, qqqq, gggg and ppppuuuubbbb_kkkkeeeeyyyy and pppprrrriiiivvvv_kkkkeeeeyyyy fields respectively.
