2019-09-27Reorganize local header filesDr. Matthias St. Pierre
Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly.

2019-09-27Reorganize private crypto header filesDr. Matthias St. Pierre
Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

2017-12-11rsa: Do not allow less than 512 bit RSA keysSebastian Andrzej Siewior
As per documentation, the RSA keys should not be smaller than 64bit (the documentation mentions something about a quirk in the prime generation algorithm). I am adding check into the code which used to be 16 for some reason. My primary motivation is to get rid of the last sentence in the documentation which suggest that typical keys have 1024 bits (instead updating it to the now default 2048). I *assume* that keys less than the 2048 bits (say 512) are used for education purposes. The 512 bits as the minimum have been suggested by Bernd Edlinger.

2017-01-08Add PSS parameter restrictions.Dr. Stephen Henson
If a key contains any PSS parameter restrictions set them during sign or verification initialisation. Parameters now become the default values for sign/verify. Digests are fixed and any attempt to change them is an error. The salt length can be modified but must not be less than the minimum value. If the key parameters are invalid then verification or signing initialisation returns an error.

2015-04-30Fix buffer overrun in RSA signingMatt Caswell
The problem occurs in EVP_PKEY_sign() when using RSA with X931 padding. It is only triggered if the RSA key size is smaller than the digest length. So with SHA512 you can trigger the overflow with anything less than an RSA 512 bit key. I managed to trigger a 62 byte overflow when using a 16 bit RSA key. This wasn't sufficient to cause a crash, although your mileage may vary. In practice RSA keys of this length are never used and X931 padding is very rare. Even if someone did use an excessively short RSA key, the chances of them combining that with a longer digest and X931 padding is very small. For these reasons I do not believe there is a security implication to this. Thanks to Kevin Wojtysiak (Int3 Solutions) and Paramjot Oberoi (Int3 Solutions) for reporting this issue.
