2017-08-04Consolidate to a single asn1_time_from_tm() functionTodd Short
Add missing ASN1_TIME functions Do some cleanup of the ASN1_TIME code. Add ASN1_TIME_normalize() to normalize ASN1_TIME structures. Add ASN1_TIME_compare() to compare two ASN1_TIME structures. Add ASN1_TIME_cmp_time_t() to compare an ASN1_TIME to time_t (generic version of ASN1_UTCTIME_cmp_time_t()). Replace '0' .. '9' compares with isdigit() Reviewed-by: Paul Dale <paul.dale@oracle.com> Reviewed-by: Rich Salz <rsalz@openssl.org> (Merged from https://github.com/openssl/openssl/pull/2753)
2017-08-03Add RAND_priv_bytes() for private keysRich Salz
Add a new global DRBG for private keys used by RAND_priv_bytes. Add BN_priv_rand() and BN_priv_rand_range() which use RAND_priv_bytes(). Change callers to use the appropriate BN_priv... function.

2017-08-03Switch from ossl_rand to DRBG randRich Salz
If RAND_add wraps around, XOR with existing. Add test to drbgtest that does the wrap-around. Re-order seeding and stop after first success. Add RAND_poll_ex() Use the DF and therefore lower RANDOMNESS_NEEDED. Also, for child DRBG's, mix in the address as the personalization bits. Centralize the entropy callbacks, from drbg_lib to rand_lib. (Conceptually, entropy is part of the enclosing application.) Thanks to Dr. Matthias St Pierre for the suggestion. Various code cleanups: -Make state an enum; inline RANDerr calls. -Add RAND_POLL_RETRIES (thanks Pauli for the idea) -Remove most RAND_seed calls from rest of library -Rename DRBG_CTX to RAND_DRBG, etc. -Move some code from drbg_lib to drbg_rand; drbg_lib is now only the implementation of NIST DRBG. -Remove blocklength Reviewed-by: Paul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/4019)

2017-07-31Fix the names of older ciphers.David Benjamin
The names of these ciphers have an "SSL_" prefix, but the RFC names use "TLS_": https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4 This dates back to these ciphers being originally defined in SSLv3. As SSLv3 is on its way out anyway and this is a new set of APIs, consistently use the TLS names.

2017-07-26Add support to free/allocate SSL buffersTodd Short
OpenSSL already has the feature of SSL_MODE_RELEASE_BUFFERS that can be set to release the read or write buffers when data has finished reading or writing. OpenSSL will automatically re-allocate the buffers as needed. This can be quite aggressive in terms of memory allocation. This provides a manual mechanism. SSL_free_buffers() will free the data buffers if there's no pending data. SSL_alloc_buffers() will realloc them; but this function is not strictly necessary, as it's still done automatically in the state machine.

Add a new config param to specify how the CSPRNG should be seeded. Illegal values or nonsensical combinations (e.g., anything other than "os" on VMS or HP VOS etc) result in build failures. Add RDSEED support. Add RDTSC but leave it disabled for now pending more investigation. Refactor and reorganization all seeding files (rand_unix/win/vms) so that they are simpler. Only require 128 bits of seeding material. Many document improvements, including why to not use RAND_add() and the limitations around using load_file/write_file. Document RAND_poll().

Standardized the -rand flag and added a new one: -rand file...
