2016-04-06KEYS: Generalise system_verify_data() to provide access to internal contentDavid Howells1-14/+7
Generalise system_verify_data() to provide access to internal content through a callback. This allows all the PKCS#7 stuff to be hidden inside this function and removed from the PE file parser and the PKCS#7 test key. If external content is not required, NULL should be passed as data to the function. If the callback is not required, that can be set to NULL. The function is now called verify_pkcs7_signature() to contrast with verify_pefile_signature() and the definitions of both have been moved into linux/verification.h along with the key_being_used_for enum.

2016-03-03X.509: Make algo identifiers text instead of enumDavid Howells1-7/+7
Make the identifier public key and digest algorithm fields text instead of enum. Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-09-01PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use themDavid Howells1-0/+9
Add OIDs for sha224, sha284 and sha512 hash algos and use them to select the hashing algorithm. Without this, something like the following error might get written to dmesg: [ 31.829322] PKCS7: Unknown OID: [32] 2.16.840.1.101.3.4.2.3 [ 31.829328] PKCS7: Unknown OID: [180] 2.16.840.1.101.3.4.2.3 [ 31.829330] Unsupported digest algo: 55 Where the 55 on the third line is OID__NR indicating an unknown OID.

2014-07-09pefile: Handle pesign using the wrong OIDVivek Goyal1-1/+7
The pesign utility had a bug where it was using OID_msIndividualSPKeyPurpose instead of OID_msPeImageDataObjId - so allow both OIDs. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Acked-by: Vivek Goyal <vgoyal@redhat.com>
2014-07-09pefile: Parse the "Microsoft individual code signing" data blobDavid Howells1-0/+120
The PKCS#7 certificate should contain a "Microsoft individual code signing" data blob as its signed content. This blob contains a digest of the signed content of the PE binary and the OID of the digest algorithm used (typically SHA256).
