Hi there,

Does U-boot take into account certificate expiration date when verifying signed images in FIT? In other words, is date stored along with the public key in DTB file?

Cheers, Andy

Hello Philippe,

looking at padding_pkcs_15_verify() in lib/rsa/rsa-verify.c I cannot find a comparison of the date on which an image was signed with the expiry date of the certificate. Shouldn't there be a check? Or did I simply look into the wrong function?

Best regards
