2020-02-12Deprecate the low level DSA functions.Pauli
Use of the low level DSA functions has been informally discouraged for a long time. We now formally deprecate them. Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/10977)

This is required in order to share code for FIPS related parameter generation and validation routinues.

2019-09-28Reorganize 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.

2019-09-28Reorganize 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.

2016-06-13Implement DSA_SIG_set0() and ECDSA_SIG_set0(), for setting signature values.TJ Saunders
SSH2 implementations which use DSA_do_verify() and ECDSA_do_verify() are given the R and S values, and the data to be signed, by the client. Thus in order to validate these signatures, SSH2 implementations will digest and sign the data -- and then pass in properly provisioned DSA_SIG and ECDSA_SIG objects. Unfortunately, the existing OpenSSL-1.1.0 APIs do not allow for directly setting those R and S values in these objects, which makes using OpenSSL for such SSH2 implementations much more difficult.

2015-03-26Simplify DSA public key handling.Dr. Stephen Henson
DSA public keys could exist in two forms: a single Integer type or a SEQUENCE containing the parameters and public key with a field called "write_params" deciding which form to use. These forms are non standard and were only used by functions containing "DSAPublicKey" in the name. Simplify code to only use the parameter form and encode the public key component directly in the DSA public key method. Reviewed-by: Richard Levitte <levitte@openssl.org>

2015-01-05Fix various certificate fingerprint issues.Dr. Stephen Henson
By using non-DER or invalid encodings outside the signed portion of a certificate the fingerprint can be changed without breaking the signature. Although no details of the signed portion of the certificate can be changed this can cause problems with some applications: e.g. those using the certificate fingerprint for blacklists. 1. Reject signatures with non zero unused bits. If the BIT STRING containing the signature has non zero unused bits reject the signature. All current signature algorithms require zero unused bits. 2. Check certificate algorithm consistency. Check the AlgorithmIdentifier inside TBS matches the one in the certificate signature. NB: this will result in signature failure errors for some broken certificates. 3. Check DSA/ECDSA signatures use DER. Reencode DSA/ECDSA signatures and compare with the original received signature. Return an error if there is a mismatch. This will reject various cases including garbage after signature (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS program for discovering this case) and use of BER or invalid ASN.1 INTEGERs (negative or with leading zeroes).
