Fixes #5849 In pull request #5503 a fallback was added which adds a random nonce of security_strength/2 bits if no nonce callback is provided. This change raised the entropy requirements form 256 to 384 bit, which can cause problems on some platforms (e.g. VMS, see issue #5849). The requirements for the nonce are given in section 8.6.7 of NIST SP 800-90Ar1: A nonce may be required in the construction of a seed during instantiation in order to provide a security cushion to block certain attacks. The nonce shall be either: a) A value with at least (security_strength/2) bits of entropy, or b) A value that is expected to repeat no more often than a (security_strength/2)-bit random string would be expected to repeat. Each nonce shall be unique to the cryptographic module in which instantiation is performed, but need not be secret. When used, the nonce shall be considered to be a critical security parameter. This commit implements a nonce of type b) in order to lower the entropy requirements during instantiation back to 256 bits. The formulation "shall be unique to the cryptographic module" above implies that the nonce needs to be unique among (with high probability) among all DRBG instances in "space" and "time". We try to achieve this goal by creating a nonce of the following form nonce = app-specific-data || high-resolution-utc-timestamp || counter Where || denotes concatenation. The application specific data can be something like the process or group id of the application. A utc timestamp is used because it increases monotonically, provided the system time is synchronized. This approach may not be perfect yet for a FIPS evaluation, but it should be good enough for the moment. This commit also harmonizes the implementation of the get_nonce() and the get_additional_data() callbacks and moves the platform specific parts from rand_lib.c into rand_unix.c, rand_win.c, and rand_vms.c.

There is a test to check that 'genrsa' doesn't accept absurdly low number of bits. Apart from that, this test is designed to check the working functionality of 'openssl genrsa', so instead of having a hard coded lower limit on the size key, let's figure out what it is.

The scrypt and RSA-PSS documents were a mixture of section 3 and section 7 material. With pre-1.1.1 OpenSSL, this is understandable, since we had a different directory layout. With 1.1.1, we've moved to the typical man-page directory layout, and the documents need to be updated accordingly. Also, the scrypt document contained a description of EVP_PKEY_CTX_set1_pbe_pass(), which is a generic function rather than an scrypt specific function, and therefore should be documented separately.

Historically we used to implement standalone base64 code for SRP. This was replaced by commit 3d3f21aa with the standard base64 processing code. However, the SRP base64 code was designed to be compatible with other SRP libraries (notably libsrp, but also others) that use a variant of standard base64. Specifically a different alphabet is used and no padding '=' characters are used. Instead 0 padding is added to the front of the string. By changing to standard base64 we change the behaviour of the API which may impact interoperability. It also means that SRP verifier files created prior to 1.1.1 would not be readable in 1.1.1 and vice versa. Instead we expand our standard base64 processing with the capability to be able to read and generate the SRP base64 variant. Reviewed-by:

Previously they were using EVP_EncodeBlock/EVP_DecodeBlock. These are low level functions that do not handle padding characters. This was causing the SRP code to fail. One side effect of using EVP_EncodeUpdate is that it inserts newlines which is not what we need in SRP so we add a flag to avoid that. Reviewed-by:

Computing the value of the GENERATED variable in the build file templates is somewhat overcomplicated, and because of possible duplication errors, changes are potentially error prone. Looking more closely at how this list is determined, it can be observed that the exact list of files to check is consistently available in all the values found in the %unified_info tables 'depends', 'sources' and 'shared_sources', and all that's needed is to filter those values so only those present as keys in the 'generate' table are left. This computation is also common for all build files, so due to its apparent complexity, we move it to common0.tmpl, with the result left in a global variable (@generated), to be consumed by all build file templates. common0.tmpl is included among the files to process when creating build files, but unlike common.tmpl, it comes first of all.

Fixes #5778, #5840 The various IS_*() macros did not work correctly for 8-bit ASCII characters with the high bit set, because the CVT(a) preprocessor macro and'ed the given ASCII value with 0x7F, effectively folding the high value range 128-255 over the low value range 0-127. As a consequence, some of the IS_*() erroneously returned TRUE. This commit fixes the issue by adding range checks instead of cutting off high order bits using a mask. In order avoid multiple evaluation of macro arguments, most of the implementation was moved from macros into a static function is_keytype(). Thanks to Румен Петров for reporting and analyzing the UTF-8 parsing issue #5840. Reviewed-by:

Original logic was "if no records found *or* last one is truncated, then leave complete records in queue." Trouble is that if we don't pass on complete records and get complete packet in opposite direction, then queued records will go back to sender. In other words complete records should always be passed on. [Possible alternative would be to match direction in reconstruct_record.] Reviewed-by:
