* Remove EVP_PKEY2PKCS8_broken() and PKCS8_set_broken()tb2018-08-241-30/+2
| | | | | | | | | | | Provide PKCS8_pkey_add1_attr_by_NID() and PKCS8_pkey_get0_attrs(). Remove the whole broken code and simplify pkcs8_priv_key_info_st accordingly. Based on OpenSSL commit 54dbf42398e23349b59f258a3dd60387bbc5ba13 plus some const that was added later. tested in a bulk build by sthen ok jsing

| | | | | | | | | | | | | | the terminating NUL. EVP_read_pw_string_min() got this wrong, leading to a one-byte buffer overrun in all callers of EVP_read_pw_string(). Found by mestre running 'openssl passwd' with MALLOC_OPTIONS including C. Fix this by doing some basic sanity checking in EVP_read_pw_string_min(). Cap the len argument at BUFSIZ and ensure that min < len as well as 0 <= min and 1 <= len. The last two checks are important as these numbers may end up in reallocarray(). ok bcook (on previous version), jsing, mestre

* make ENGINE_finish() succeed on NULL and simplify callers as intb2018-04-144-36/+19
| | | | | | | | | | | OpenSSL commit 7c96dbcdab9 by Rich Salz. This cleans up the caller side quite a bit and reduces the number of lines enclosed in #ifndef OPENSSL_NO_ENGINE. codesearch.debian.net shows that almost nothing checks the return value of ENGINE_finish(). While there, replace a few nearby 'if (!ptr)' with 'if (ptr == NULL)'. ok jsing, tested by & ok inoguchi
* Bring in compatibility for OpenSSL 1.1 style init functions.beck2018-03-172-5/+38
| | | | | | | | | This adds OPENSSL_init_crypto and OPENSSL_init_ssl, as well thread safety modifications for the existing LibreSSL init functions. The initialization routines are called automatically by the normal entry points into the library, as in newer OpenSSL ok jsing@, nits by tb@ and deraadt@

| | | | No change to generated assembly excluding line numbers.
* Explicitly export a list of symbols from libcrypto.jsing2016-12-211-1/+5
| | | | | | | | | | | | | | | | Move the "internal" BN functions from bn.h to bn_lcl.h and stop exporting the bn_* symbols. These are documented as only being intended for internal use, so why they were placed in a public header is beyond me... This hides 363 previously exported symbols, most of which exist in headers that are not installed and were never intended to be public. This also removes a few crusty old things that should have died long ago (like _ossl_old_des_read_pw). But don't worry... there are still 3451 symbols exported from the library. With input and testing from inoguchi@. ok beck@ inoguchi@

While there, turn it from an array of two 32-bit ints into a properly aligned 64-bit int. Use of OPENSSL_ia32_P is now restricted to the assembler parts. C code will now always use OPENSSL_cpu_caps() and check for the proper bits in the whole 64-bit word it returns. i386 tests and ok jsing@

* deprecate EVP_EncryptFinal(), EVP_DecryptFinal() and EVP_CipherFinal()bcook2016-09-031-3/+15
| | | | | | | | | | This switches EVP_CipherFinal() to work as EVP_EncryptFinal() and EVP_DecryptFinal() do, always clearing the cipher context on completion. Indicate that, since it is not possible to tell whether this function will clear the context (the API has changed over time in OpenSSL), it is better to use the _ex() variants and explicitly clear instead. ok beck@
* deprecate internal use of EVP_[Cipher|Encrypt|Decrypt]_Final.beck2016-05-302-8/+16
| | | | | | | 14 years ago these were changed in OpenSSL to be the same as the _ex functions. We use the _ex functions only internally to ensure it is obvious the ctx must be cleared. ok bcook@
