d2i_DSAPublicKey

Section: OpenSSL (3)
Updated: 2015-01-22
Index Return to Main Contents
 

NAME

d2i_DSAPublicKey, i2d_DSAPublicKey, d2i_DSAPrivateKey, i2d_DSAPrivateKey, d2i_DSA_PUBKEY, i2d_DSA_PUBKEY, d2i_DSAparams, i2d_DSAparams, d2i_DSA_SIG, i2d_DSA_SIG - DSA key encoding and parsing functions.  

SYNOPSIS

 #include <openssl/dsa.h>
 #include <openssl/x509.h>

 DSA * d2i_DSAPublicKey(DSA **a, const unsigned char **pp, long length);

 int i2d_DSAPublicKey(const DSA *a, unsigned char **pp);

 DSA * d2i_DSA_PUBKEY(DSA **a, const unsigned char **pp, long length);

 int i2d_DSA_PUBKEY(const DSA *a, unsigned char **pp);

 DSA * d2i_DSAPrivateKey(DSA **a, const unsigned char **pp, long length);

 int i2d_DSAPrivateKey(const DSA *a, unsigned char **pp);

 DSA * d2i_DSAparams(DSA **a, const unsigned char **pp, long length);

 int i2d_DSAparams(const DSA *a, unsigned char **pp);

 DSA * d2i_DSA_SIG(DSA_SIG **a, const unsigned char **pp, long length);

 int i2d_DSA_SIG(const DSA_SIG *a, unsigned char **pp);

 

DESCRIPTION

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 Dss-Parms structure as defined in RFC2459.

d2i_DSA_SIG(), i2d_DSA_SIG() decode and encode a DSA signature using a Dss-Sig-Value 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) manual page.  

NOTES

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

The DSAPublicKey functions use an non standard format the actual data encoded depends on the value of the write_params field of the a key parameter. If write_params is zero then only the pub_key field is encoded as an INTEGER. If write_params is 1 then a SEQUENCE consisting of the p, q, g and pub_key respectively fields are encoded.

The DSAPrivateKey functions also use a non standard structure consiting consisting of a SEQUENCE containing the p, q, g and pub_key and priv_key fields respectively.
