This function is used to parse the result of dumpKeys. It's no longer
needed as we are now parsing the public keys from the zipfile.

For RSA keys, check if it has a 2048 bits modulus, and its public
exponent is 3 or 65537. For EC keys, check if the field size is 256
bits for its curve.

Add a function to parse the zip archive and load the certificate from
all the zip entries with the suffix "x509.pem".
Bug: 116655889
Test: unittests pass
Change-Id: I93bf7aef7462c0623e89fc2d466d7af2d3a758bc
We used to convert a pem certificate file to some intermediate plain
text format; and parse that format under recovery mode. This is
uncessary since the x509.pem can be directly parsed with openssl
functions.
Add the function to load the public key from one x509.pem file and
corresponding unit tests. And we will add more cls to extract the pem
files from otacert.zip later.

Would be good to mark them as const, so
class variables are not changed by coincidence

A follow-up to commit 5e535014dd.
Also clean up Android.mk, since libverifier no longer needs anything
from libminui.

verify_file() has a dependency on the global variable of 'ui' for
posting the verification progress, which requires the users of
libverifier to provide a UI instance.
This CL adds an optional argument to verify_file() so that it can
post the progress through the provided callback function. As a result,
we can drop the MockUI class in verifier_test.cpp.
Test: recovery_component_test passes.
Test: verify_file() posts progress update when installing an OTA.

The 'signature_start' variable marks the location of the signature
from the end of a zip archive. And a boundary check is missing where
'signature_start' should be within the EOCD comment field. This causes
problems when sideloading a malicious package. Also add a corresponding
test.
Bug: 31914369
Test: Verification fails correctly when sideloading recovery_test.zip on
angler.

(cherry-picked from f69e6a9475)
This reverts commit 8584fcf677.
This CL re-lands commit c0319b60f5.
The "stage" and "reason" variables are now declared as global by
dropping the static qualifier, because they may be used by vendor
recovery libraries.

- Remove the duplicate gCurrentUI variable in recovery.cpp;
- Refactor the load/save of locale functions;
- Clean up ui_print() to get rid of 256-byte buffer limit;
- Declare ui in common.h;
- Move the typedef of Volume into roots.h.
Test: Build and boot into recovery image.

This fixes build errors with BoringSSL master. (The cpp file uses functions
from bn.h and neither it nor the header includes it.)

This changes the verification code in bootable/recovery to use
BoringSSL instead of mincrypt.
Cherry-pick of 452df6d99c, with
merge conflict resolution, extra logging in verifier.cpp, and
an increase in the hash chunk size from 4KiB to 1MiB.

Change-Id: Ia5f799bc8dcc036a0ffae5eaa8d9f6e09abd031c
Changes minzip and recovery's file signature verification to work on
memory regions, rather than files.
For packages which are regular files, install.cpp now mmap()s them
into memory and then passes the mapped memory to the verifier and to
the minzip library.
Support for files which are raw block maps (which will be used when we
have packages written to encrypted data partitions) is present but
largely untested so far.

This adds support for key version 5 which is an EC key using the NIST
P-256 curve parameters. OTAs may be signed with these keys using the
ECDSA signature algorithm with SHA-256.

Move all the functions in ui.c to be members of a ScreenRecoveryUI
class, which is a subclass of an abstract RecoveryUI class. Recovery
then creates a global singleton instance of this class and then invoke
the methods to drive the UI. We use this to allow substitution of a
different RecoveryUI implementation for devices with radically
different form factors (eg, that don't have a screen).
