don't drop leading zeroes when performing generic ecdsa signing (#357)

call ret.FillBytes() instead of ret.Bytes() to preserve leading zeroes that may have been dropped when converting the digest to an integer

Bump github.com/google/go-tpm from 0.3.4 to 0.9.0 (#337)

Bump go-tpm version (#264)

Certify now returns raw TPMT_SIGNATURE, so no need to pack it.

AKPublic.VerifyAll: Additionally validate input parameters (#263)

Merge pull request from GHSA-99cg-575x-774p

* AKPublic.Verify: Return an error if a provided PCR of the correct
   digest was not included in the quote.
 * AKPublic.VerifyAll: Implement VerifyAll method, which can cross-check
   that provided PCRs were covered by quotes across PCR banks.
 * PCR.QuoteVerified(): Introduce getter method to expose whether a
   PCR value was covered during quote verification.

Parse TCG_PCClientPCREvent structures with an eventSize of 0 (#212)

Fix integer overflow in digest parsing (#211)

Minor fixes and additions (#207)

* replace ReadPublic() by DecodePublic() when creating and loading keys: the current implementation calls ReadPublic() even if public data is already accessible
* drop handle() from the ak interface: it is unnecessary
* add Blobs() to attest.Key: to allow agnostic key marshaling
