Certificates contain cryptography information for verifying Signatures. These certificates are also signed. The parent/child relationship between certificates, makes all the certificates effectively signed by 'Root', the public key for which is stored in NATIVE_FIRM. | Certificates contain cryptography information for verifying Signatures.

== Signature == | |||
The signature method used to sign the certificate can be determined by checking the Signature Type: | |||
{{Signature Types}} | |||
The hash for the signature is calculated over the actual certificate data(from the start of the "Issuer", to the end of the "Public Key", aligned to 0x40 bytes). | |||
