The new API functions have "_ex" + postfixes and the older functions are reimplemented as wrappers for + the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide + declarations of the old functions to help (graceful) attempts to + migrate to the new functions. Also, the new key-generation API + functions operate on a caller-supplied key-structure and return + success/failure rather than returning a key or NULL - this is to + help make "keygen" another member function of RSA_METHOD etc. + [Geoff Thorpe] + *) Add the ASN.1 structures and functions for CertificatePair, which is defined as follows (according to X.509_4thEditionDraftV6.pdf): diff --git a/crypto/bn/Makefile.ssl b/crypto/bn/Makefile.ssl index d0b64585ed..459a0693ed 100644 --- a/crypto/bn/Makefile.ssl +++ b/crypto/bn/Makefile.ssl @@ -39,12 +39,14 @@ LIB=$(TOP)/libcrypto.a LIBSRC= bn_add.c bn_div.c bn_exp.c bn_lib.c bn_ctx.c bn_mul.c bn_mod.c \ bn_print.c bn_rand.c bn_shift.c bn_word.c bn_blind.c \ bn_kron.c bn_sqrt.c bn_gcd.c bn_prime.c bn_err.c bn_sqr.c bn_asm.c \ - bn_recp.c bn_mont.c bn_mpi.c bn_exp2.c bn_gf2m.c bn_nist.c + bn_recp.c bn_mont.c bn_mpi.c bn_exp2.c bn_gf2m.c bn_nist.c \ + bn_depr.c LIBOBJ= bn_add.o bn_div.o bn_exp.o bn_lib.o bn_ctx.o bn_mul.o bn_mod.o \ bn_print.o bn_rand.o bn_shift.o bn_word.o bn_blind.o \ bn_kron.o bn_sqrt.o bn_gcd.o bn_prime.o bn_err.o bn_sqr.o $(BN_ASM) \ - bn_recp.o bn_mont.o bn_mpi.o bn_exp2.o bn_gf2m.o bn_nist.o + bn_recp.o bn_mont.o bn_mpi.o bn_exp2.o bn_gf2m.o bn_nist.o \ + bn_depr.o SRC= $(LIBSRC) diff --git a/crypto/bn/bn.h b/crypto/bn/bn.h index 403add94b0..c1b5b41935 100644 --- a/crypto/bn/bn.h +++ b/crypto/bn/bn.h @@ -287,6 +287,23 @@ typedef struct bn_recp_ctx_st int flags; } BN_RECP_CTX; +/* Used for slow "generation" functions. */ +typedef struct bn_gencb_st BN_GENCB; +struct bn_gencb_st + { + unsigned int ver; /* To handle binary (in)compatibility */ + void *arg; /* callback-specific data */ + union + { + /* if(ver==1) - handles old style callbacks */ + void (*cb_1)(int, int, void *); + /* if(ver==2) - new callback style */ + int (*cb_2)(int, int, BN_GENCB *); + }; + }; +/* Wrapper function to make using BN_GENCB easier, */ +int BN_GENCB_call(BN_GENCB *cb, int a, int b); + #define BN_prime_checks 0 /* default: select number of iterations based on the size of the number */ @@ -431,6 +448,9 @@ BIGNUM *BN_mod_inverse(BIGNUM *ret, const BIGNUM *a, const BIGNUM *n,BN_CTX *ctx); BIGNUM *BN_mod_sqrt(BIGNUM *ret, const BIGNUM *a, const BIGNUM *n,BN_CTX *ctx); + +/* Deprecated versions */ +#ifndef OPENSSL_NO_DEPRECATED BIGNUM *BN_generate_prime(BIGNUM *ret,int bits,int safe, const BIGNUM *add, const BIGNUM *rem, void (*callback)(int,int,void *),void *cb_arg); @@ -440,6 +460,14 @@ int BN_is_prime(const BIGNUM *p,int nchecks, int BN_is_prime_fasttest(const BIGNUM *p,int nchecks, void (*callback)(int,int,void *),BN_CTX *ctx,void *cb_arg, int do_trial_division); +#endif /* !defined(OPENSSL_NO_DEPRECATED) */ + +/* Newer versions */ +int BN_generate_prime_ex(BIGNUM *ret,int bits,int safe, const BIGNUM *add, + const BIGNUM *rem, BN_GENCB *cb); +int BN_is_prime_ex(const BIGNUM *p,int nchecks, BN_CTX *ctx, BN_GENCB *cb); +int BN_is_prime_fasttest_ex(const BIGNUM *p,int nchecks, BN_CTX *ctx, + int do_trial_division, BN_GENCB *cb); BN_MONT_CTX *BN_MONT_CTX_new(void ); void BN_MONT_CTX_init(BN_MONT_CTX *ctx); diff --git a/crypto/bn/bn_depr.c b/crypto/bn/bn_depr.c new file mode 100644 index 0000000000..76c349833c --- /dev/null +++ b/crypto/bn/bn_depr.c @@ -0,0 +1,114 @@ +/* crypto/bn/bn_depr.c */ +/* ==================================================================== + * Copyright (c) 1998-2002 The OpenSSL Project.
