From d0a21970fdc0fbbfc7ad31bc135f5a8fde1d3d49 Mon Sep 17 00:00:00 2001 From: tb <> Date: Sat, 26 Nov 2022 16:08:57 +0000 Subject: Make internal header file names consistent Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names used for internal headers. Move all these headers we inherited from OpenSSL to *_local.h, reserving the name *_internal.h for our own code. Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h. constant_time_locl.h is moved to constant_time.h since it's special. Adjust all .c files in libcrypto, libssl and regress. The diff is mechanical with the exception of tls13_quic.c, where #include was fixed manually. discussed with jsing, no objection bcook --- src/lib/libcrypto/rsa/rsa_local.h | 94 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 94 insertions(+) create mode 100644 src/lib/libcrypto/rsa/rsa_local.h (limited to 'src/lib/libcrypto/rsa/rsa_local.h') diff --git a/src/lib/libcrypto/rsa/rsa_local.h b/src/lib/libcrypto/rsa/rsa_local.h new file mode 100644 index 0000000000..b438ab4eec --- /dev/null +++ b/src/lib/libcrypto/rsa/rsa_local.h @@ -0,0 +1,94 @@ +/* $OpenBSD: rsa_local.h,v 1.1 2022/11/26 16:08:54 tb Exp $ */ + +__BEGIN_HIDDEN_DECLS + +#define RSA_MIN_MODULUS_BITS 512 + +/* Macros to test if a pkey or ctx is for a PSS key */ +#define pkey_is_pss(pkey) (pkey->ameth->pkey_id == EVP_PKEY_RSA_PSS) +#define pkey_ctx_is_pss(ctx) (ctx->pmeth->pkey_id == EVP_PKEY_RSA_PSS) + +struct rsa_meth_st { + char *name; + int (*rsa_pub_enc)(int flen, const unsigned char *from, + unsigned char *to, RSA *rsa, int padding); + int (*rsa_pub_dec)(int flen, const unsigned char *from, + unsigned char *to, RSA *rsa, int padding); + int (*rsa_priv_enc)(int flen, const unsigned char *from, + unsigned char *to, RSA *rsa, int padding); + int (*rsa_priv_dec)(int flen, const unsigned char *from, + unsigned char *to, RSA *rsa, int padding); + int (*rsa_mod_exp)(BIGNUM *r0, const BIGNUM *I, RSA *rsa, + BN_CTX *ctx); /* Can be null */ + int (*bn_mod_exp)(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, + const BIGNUM *m, BN_CTX *ctx, BN_MONT_CTX *m_ctx); /* Can be null */ + int (*init)(RSA *rsa); /* called at new */ + int (*finish)(RSA *rsa); /* called at free */ + int flags; /* RSA_METHOD_FLAG_* things */ + char *app_data; /* may be needed! */ +/* New sign and verify functions: some libraries don't allow arbitrary data + * to be signed/verified: this allows them to be used.
