The following API groups are extended with a new init function, as well as an update and final function, to allow the use of explicitly fetched signature implementations for any composite signature algorithm, like "sha1WithRSAEncryption": - EVP_PKEY_sign - EVP_PKEY_verify - EVP_PKEY_verify_recover To support this, providers are required to add a few new functions, not the least one that declares what key types an signature implementation supports. While at this, the validity check in evp_signature_from_algorithm() is also refactored; the SIGNATURE provider functionality is too complex for counters. It's better, or at least more readable, to check function combinations.

Adding new libraries
When adding a new sub-library to OpenSSL, assign it a library number
ERR_LIB_XXX, define a macro XXXerr() (both in err.h), add its
name to ERR_str_libraries[] (in crypto/err/err.c), and add
ERR_load_XXX_strings() to the ERR_load_crypto_strings() function
(in crypto/err/err_all.c). Finally, add an entry:
L XXX xxx.h xxx_err.c
to crypto/err/openssl.ec, and add xxx_err.c to the Makefile.
Running make errors will then generate a file xxx_err.c, and
add all error codes used in the library to xxx.h.
Additionally the library include file must have a certain form. Typically it will initially look like this:
#ifndef HEADER_XXX_H
#define HEADER_XXX_H
#ifdef __cplusplus
extern "C" {
#endif
/* Include files */
#include <openssl/bio.h>
#include <openssl/x509.h>
/* Macros, structures and function prototypes */
/* BEGIN ERROR CODES */
The BEGIN ERROR CODES sequence is used by the error code
generation script as the point to place new error codes, any text
after this point will be overwritten when make errors is run.
The closing #endif etc will be automatically added by the script.
The generated C error code file xxx_err.c will load the header
files stdio.h, openssl/err.h and openssl/xxx.h so the
header file must load any additional header files containing any
definitions it uses.
Adding new error codes
Instead of manually adding error codes into crypto/err/openssl.txt,
it is recommended to leverage make update for error code generation.
The target will process relevant sources and generate error codes for
any used error codes.
If an error code is added manually into crypto/err/openssl.txt,
subsequent make update has no effect.
