4977b4e928 PEM_def_callback(): don't loop because of too short password given
That error is already caught by EVP_read_pw_string_min, and causes
this function to return -1, so the code detecting too short passwords
in this function is practically dead.

Fixes #5465

b0143b9752 Fix type error in PEM processing
The get_name() helper was using a variable of type size_t to hold the
result of BIO_gets(), but BIO_gets() returns int and makes use of negative
values to indicate error conditions.

Change the type of the local variable to match, and propagate that
through to other places in the file to avoid -Wsign-compare issues.

a1df06b363 This has been added to avoid the situation where some host ctype.h functions
return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will
work for both signed and unsigned character inputs.

75e2c87765 Switch from ossl_rand to DRBG rand
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

48feaceb53 Remove the possibility to disable the UI module entirely
Instead, make it possible to disable the console reader that's part of
the UI module.  This makes it possible to use the UI API and other UI
methods in environments where the console reader isn't useful.

To disable the console reader, configure with 'no-ui-console' /
'disable-ui-console'.

'no-ui' / 'disable-ui' is now an alias for  'no-ui-console' /
'disable-ui-console'.

44612e0a81 Make PEM_read_{,bio_}PrivateKey use secmem
We now have a version of PEM_read_bytes that can use temporary
buffers allocated from the secure heap; use them to handle this
sensitive information.

Note that for PEM_read_PrivateKey, the i/o still goes through
stdio since the input is a FILE pointer.  Standard I/O performs
additional buffering, which cannot be changed to use the OpenSSL
secure heap for temporary storage.  As such, it is recommended
to use BIO_new_file() and PEM_read_bio_PrivateKey() instead.

when needed, and reimplement PEM_bytes_read() as a wrapper around
the _flags helper.

Add documentation for PEM_bytes_read_bio() and the new secmem variant.

204afd81b1 Add PEM_read_bio_ex
The extended function includes a 'flags' argument to allow callers
to specify different requested behaviors.  In particular, callers can
request that temporary storage buffers are allocated from the secure heap,
which could be relevant when loading private key material.

Refactor PEM_read_bio to use BIO_mems instead of BUFs directly,
use some helper routines to reduce the overall function length, and make
some of the checks more reasonable.

b01e1644d7 Fix: PEM_read_bio_PrivateKey with no-ui / no-stdio
If openssl is compiled with no-ui or no-stdio, then PEM_read_bio_PrivateKey fails if a password but no callback is provided.

The reason is that the premature return in the PEM_def_callback implementation when OPENSSL_NO_STDIO or OPENSSL_NO_UI is defined, comes too early.

This patch moves the ifdef block to the correct place.
