.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "d2i_RSAPublicKey 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.

Header "SYNOPSIS" .Vb 2 #include <openssl/rsa.h> #include <openssl/x509.h> \& RSA * d2i_RSAPublicKey(RSA **a, unsigned char **pp, long length); \& int i2d_RSAPublicKey(RSA *a, unsigned char **pp); \& RSA * d2i_RSA_PUBKEY(RSA **a, unsigned char **pp, long length); \& int i2d_RSA_PUBKEY(RSA *a, unsigned char **pp); \& RSA * d2i_RSAPrivateKey(RSA **a, unsigned char **pp, long length); \& int i2d_RSAPrivateKey(RSA *a, unsigned char **pp); \& int i2d_Netscape_RSA(RSA *a, unsigned char **pp, int (*cb)()); \& RSA * d2i_Netscape_RSA(RSA **a, unsigned char **pp, long length, int (*cb)()); .Ve Header "DESCRIPTION" \fId2i_RSAPublicKey() and i2d_RSAPublicKey() decode and encode a PKCS#1 RSAPublicKey structure.

\fId2i_RSA_PUBKEY() and i2d_RSA_PUBKEY() decode and encode an \s-1RSA\s0 public key using a SubjectPublicKeyInfo (certificate public key) structure.

\fId2i_RSAPrivateKey(), i2d_RSAPrivateKey() decode and encode a PKCS#1 RSAPrivateKey structure.

\fId2i_Netscape_RSA(), i2d_Netscape_RSA() decode and encode an \s-1RSA\s0 private key in \s-1NET\s0 format.

The usage of all of these functions is similar to the d2i_X509() and \fIi2d_X509() described in the d2i_X509\|(3) manual page.

Header "NOTES" The \s-1RSA\s0 structure passed to the private key encoding functions should have all the PKCS#1 private key components present.

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

The \s-1NET\s0 format functions are present to provide compatibility with certain very old software. This format has some severe security weaknesses and should be avoided if possible.
