-FastBoot Version 0.4
-----------------------
-
-The fastboot protocol is a mechanism for communicating with bootloaders
-over USB. It is designed to be very straightforward to implement, to
-allow it to be used across a wide range of devices and from hosts running
-Linux, Windows, or OSX.
-
-
-Basic Requirements
-------------------
-
-* Two bulk endpoints (in, out) are required
-* Max packet size must be 64 bytes for full-speed and 512 bytes for
- high-speed USB
-* The protocol is entirely host-driven and synchronous (unlike the
- multi-channel, bi-directional, asynchronous ADB protocol)
-
-
-Transport and Framing
----------------------
-
-1. Host sends a command, which is an ascii string in a single
- packet no greater than 64 bytes.
-
-2. Client response with a single packet no greater than 64 bytes.
- The first four bytes of the response are "OKAY", "FAIL", "DATA",
- or "INFO". Additional bytes may contain an (ascii) informative
- message.
-
- a. INFO -> the remaining 60 bytes are an informative message
- (providing progress or diagnostic messages). They should
- be displayed and then step #2 repeats
-
- b. FAIL -> the requested command failed. The remaining 60 bytes
- of the response (if present) provide a textual failure message
- to present to the user. Stop.
-
- c. OKAY -> the requested command completed successfully. Go to #5
-
- d. DATA -> the requested command is ready for the data phase.
- A DATA response packet will be 12 bytes long, in the form of
- DATA00000000 where the 8 digit hexidecimal number represents
- the total data size to transfer.
-
-3. Data phase. Depending on the command, the host or client will
- send the indicated amount of data. Short packets are always
- acceptable and zero-length packets are ignored. This phase continues
- until the client has sent or received the number of bytes indicated
- in the "DATA" response above.
-
-4. Client responds with a single packet no greater than 64 bytes.
- The first four bytes of the response are "OKAY", "FAIL", or "INFO".
- Similar to #2:
-
- a. INFO -> display the remaining 60 bytes and return to #4
-
- b. FAIL -> display the remaining 60 bytes (if present) as a failure
- reason and consider the command failed. Stop.
-
- c. OKAY -> success. Go to #5
-
-5. Success. Stop.
-
-
-Example Session
----------------
-
-Host: "getvar:version" request version variable
-
-Client: "OKAY0.4" return version "0.4"
-
-Host: "getvar:nonexistant" request some undefined variable
-
-Client: "OKAY" return value ""
-
-Host: "download:00001234" request to send 0x1234 bytes of data
-
-Client: "DATA00001234" ready to accept data
-
-Host: < 0x1234 bytes > send data
-
-Client: "OKAY" success
-
-Host: "flash:bootloader" request to flash the data to the bootloader
-
-Client: "INFOerasing flash" indicate status / progress
- "INFOwriting flash"
- "OKAY" indicate success
-
-Host: "powerdown" send a command
-
-Client: "FAILunknown command" indicate failure
-
-
-Command Reference
------------------
-
-* Command parameters are indicated by printf-style escape sequences.
-
-* Commands are ascii strings and sent without the quotes (which are
- for illustration only here) and without a trailing 0 byte.
-
-* Commands that begin with a lowercase letter are reserved for this
- specification. OEM-specific commands should not begin with a
- lowercase letter, to prevent incompatibilities with future specs.
-
- "getvar:%s" Read a config/version variable from the bootloader.
- The variable contents will be returned after the
- OKAY response.
-
- "download:%08x" Write data to memory which will be later used
- by "boot", "ramdisk", "flash", etc. The client
- will reply with "DATA%08x" if it has enough
- space in RAM or "FAIL" if not. The size of
- the download is remembered.
-
- "verify:%08x" Send a digital signature to verify the downloaded
- data. Required if the bootloader is "secure"
- otherwise "flash" and "boot" will be ignored.
-
- "flash:%s" Write the previously downloaded image to the
- named partition (if possible).
-
- "erase:%s" Erase the indicated partition (clear to 0xFFs)
-
- "boot" The previously downloaded data is a boot.img
- and should be booted according to the normal
- procedure for a boot.img
-
- "continue" Continue booting as normal (if possible)
-
- "reboot" Reboot the device.
-
- "reboot-bootloader" Reboot back into the bootloader.
- Useful for upgrade processes that require upgrading
- the bootloader and then upgrading other partitions
- using the new bootloader.
-
- "powerdown" Power off the device.
-
-
-
-Client Variables
-----------------
-
-The "getvar:%s" command is used to read client variables which
-represent various information about the device and the software
-on it.
-
-The various currently defined names are:
-
- version Version of FastBoot protocol supported.
- It should be "0.3" for this document.
-
- version-bootloader Version string for the Bootloader.
-
- version-baseband Version string of the Baseband Software
-
- product Name of the product
-
- serialno Product serial number
-
- secure If the value is "yes", this is a secure
- bootloader requiring a signature before
- it will install or boot images.
-
-Names starting with a lowercase character are reserved by this
-specification. OEM-specific names should not start with lowercase
-characters.

+ "reboot" Reboot the device.
+
+ "reboot-bootloader" Reboot back into the bootloader.
+ Useful for upgrade processes that require upgrading
+ the bootloader and then upgrading other partitions
+ using the new bootloader.
+
+ "powerdown" Power off the device.

+
+
+Client Variables
+----------------
+
+The "getvar:%s" command is used to read client variables which
+represent various information about the device and the software
+on it.
+
+The various currently defined names are:
+
+ version Version of FastBoot protocol supported.
+ It should be "0.3" for this document.
+
+ version-bootloader Version string for the Bootloader.
+
+ version-baseband Version string of the Baseband Software
+
+ product Name of the product
+
+ serialno Product serial number
+
+ secure If the value is "yes", this is a secure
+ bootloader requiring a signature before
+ it will install or boot images.
+
+Names starting with a lowercase character are reserved by this
+specification. OEM-specific names should not start with lowercase
+characters.
Overview
========
-The protocol that is used over USB and UDP is described in the
-``README.android-fastboot-protocol`` file in the same directory.
+The protocol that is used over USB and UDP is described in
+``doc/android/fastboot-protocol.txt``.
The current implementation supports the following standard commands:
Test passed
-Hardware Signing with PKCS#11
------------------------------
+Hardware Signing with PKCS#11 or with HSM
+-----------------------------------------
Securely managing private signing keys can challenging, especially when the
keys are stored on the file system of a computer that is connected to the
device.
Requirements:
-Smartcard/USB token/HSM which can work with the pkcs11 engine
+Smartcard/USB token/HSM which can work with some openssl engine
openssl
+
+For pkcs11 engine usage:
libp11 (provides pkcs11 engine)
p11-kit (recommended to simplify setup)
opensc (for smartcards and smartcard like USB devices)
gnutls (recommended for key generation, p11tool)
-The following examples use the Nitrokey Pro. Instructions for other devices may vary.
+For generic HSMs respective openssl engine must be installed and locateable by
+openssl. This may require setting up LD_LIBRARY_PATH if engine is not installed
+to openssl's default search paths.
+
+PKCS11 engine support forms "key id" based on "keydir" and with
+"key-name-hint". "key-name-hint" is used as "object" name and "keydir" if
+defined is used to define (prefix for) which PKCS11 source is being used for
+lookup up for the key.
+
+PKCS11 engine key ids:
+ "pkcs11:<keydir>;object=<key-name-hint>;type=<public|private>"
+or
+ "pkcs11:object=<key-name-hint>;type=<public|private>",
+
+Generic HSM engine support forms "key id" based on "keydir" and with
+"key-name-hint". If "keydir" is specified for mkimage it is used as a prefix in
+"key id" and is appended with "key-name-hint".
+
+Generic engine key ids:
+ "<keydir><key-name-hint>"
+or
+ "<key-name-hint>"
+
+As mkimage does not at this time support prompting for passwords HSM may need
+key preloading wrapper to be used when invoking mkimage.
+
+The following examples use the Nitrokey Pro using pkcs11 engine. Instructions
+for other devices may vary.
