.. 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 >0, 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 "DSA_SET_METHOD 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
DSA_set_default_method, DSA_get_default_method, DSA_set_method, DSA_new_method, DSA_OpenSSL - select DSA method Header "SYNOPSIS" .Vb 1 #include <openssl/dsa.h> \& void DSA_set_default_method(const DSA_METHOD *meth); \& const DSA_METHOD *DSA_get_default_method(void); \& int DSA_set_method(DSA *dsa, const DSA_METHOD *meth); \& DSA *DSA_new_method(ENGINE *engine); \& DSA_METHOD *DSA_OpenSSL(void); .Ve Header "DESCRIPTION" A \s-1DSA_METHOD\s0 specifies the functions that OpenSSL uses for \s-1DSA\s0 operations. By modifying the method, alternative implementations such as hardware accelerators may be used. \s-1IMPORTANT:\s0 See the \s-1NOTES\s0 section for important information about how these \s-1DSA API\s0 functions are affected by the use of \s-1ENGINE\s0 \s-1API\s0 calls.

Initially, the default \s-1DSA_METHOD\s0 is the OpenSSL internal implementation, as returned by DSA_OpenSSL().

\fBDSA_set_default_method() makes meth the default method for all \s-1DSA\s0 structures created later. \fB\s-1NB\s0: This is true only whilst no \s-1ENGINE\s0 has been set as a default for \s-1DSA,\s0 so this function is no longer recommended. This function is not thread-safe and should not be called at the same time as other OpenSSL functions.

\fBDSA_get_default_method() returns a pointer to the current default \s-1DSA_METHOD.\s0 However, the meaningfulness of this result is dependent on whether the \s-1ENGINE API\s0 is being used, so this function is no longer recommended.

\fBDSA_set_method() selects meth to perform all operations using the key \fBrsa. This will replace the \s-1DSA_METHOD\s0 used by the \s-1DSA\s0 key and if the previous method was supplied by an \s-1ENGINE,\s0 the handle to that \s-1ENGINE\s0 will be released during the change. It is possible to have \s-1DSA\s0 keys that only work with certain \s-1DSA_METHOD\s0 implementations (e.g. from an \s-1ENGINE\s0 module that supports embedded hardware-protected keys), and in such cases attempting to change the \s-1DSA_METHOD\s0 for the key can have unexpected results. See DSA_meth_new for information on constructing custom \s-1DSA_METHOD\s0 objects;

\fBDSA_new_method() allocates and initializes a \s-1DSA\s0 structure so that engine will be used for the \s-1DSA\s0 operations. If engine is \s-1NULL,\s0 the default engine for \s-1DSA\s0 operations is used, and if no default \s-1ENGINE\s0 is set, the \s-1DSA_METHOD\s0 controlled by DSA_set_default_method() is used.

Header "RETURN VALUES" \fBDSA_OpenSSL() and DSA_get_default_method() return pointers to the respective \fB\s-1DSA_METHOD\s0s.

\fBDSA_set_default_method() returns no value.

\fBDSA_set_method() returns nonzero if the provided meth was successfully set as the method for dsa (including unloading the \s-1ENGINE\s0 handle if the previous method was supplied by an \s-1ENGINE\s0).

\fBDSA_new_method() returns \s-1NULL\s0 and sets an error code that can be obtained by ERR_get_error\|(3) if the allocation fails. Otherwise it returns a pointer to the newly allocated structure.
