2021-08-16dm: crypto: Define UCLASS API for ECDSA signature verificationAlexandru Gagniuc1-0/+39
Define a UCLASS API for verifying ECDSA signatures. Unlike UCLASS_MOD_EXP, which focuses strictly on modular exponentiation, the ECDSA class focuses on verification. This is done so that it better aligns with mach-specific implementations, such as stm32mp.

2020-07-22lib: crypto: export and enhance pkcs7_verify_one()AKASHI Takahiro1-1/+8
The function, pkcs7_verify_one(), will be utilized to rework signature verification logic aiming to support intermediate certificates in "chain of trust." To do that, its function interface is expanded, adding an extra argument which is expected to return the last certificate in trusted chain. Then, this last one must further be verified with signature database, db and/or dbx. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
2020-07-22lib: crypto: add public_key_verify_signature()AKASHI Takahiro1-1/+1
This function will be called from x509_check_for_self_signed() and pkcs7_verify_one(), which will be imported from linux in a later patch. While it does exist in linux code and has a similar functionality of rsa_verify(), it calls further linux-specific interfaces inside. That could lead to more files being imported from linux. So simply re-implement it here instead of re-using the code. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org>
2020-07-12lib/crypto: use qualified path for x509_parser.hHeinrich Schuchardt1-1/+1
Use the path relative to /include for x509_parser.h in pkcs7_parser.h. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-05-04lib/crypto, efi_loader: move some headers to include/cryptoAKASHI Takahiro2-0/+130
Pkcs7_parse.h and x509_parser.h are used in UEFI subsystem, in particular, secure boot. So move them to include/crypto to avoid relative paths. Suggested-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Don't include include x509_parser.h twice.
