IPSW
IPSW, iPhone Software, is a file format used to install iOS, iPadOS, tvOS, HomePod, and most recently, macOS firmware for devices equipped with Apple silicon. All Apple devices share the same IPSW file format for iOS firmware and their derivatives, allowing users to flash their devices through Finder or iTunes on macOS or Windows, respectively. Users can flash Apple silicon Macs through Apple Configurator 2. Structure The .ipsw file itself is a compressed archive file (renamed Zip archive) containing at least three Apple Disk Image files with one containing the root file system of the OS and two ram disks for restore and update. tvOS, audioOS and macOS also include a disk image for the recovery environment (recoveryOS). The file also holds the kernel caches, and a "Firmware" folder which contains iBoot, LLB (Low-Level Bootloader), iBSS (iBoot Single Stage), iBEC (iBoot Epoch Change), the Secure Enclave Processor firmware, the Device Tree, Firmware Images (Apple logo, ba ...

IPadOS
iPadOS is a mobile operating system developed by Apple Inc. for its iPad line of tablet computers. It is a rebranded variant of iOS, the operating system used by Apple's iPhones, renamed to reflect the diverging features of the two product lines, particularly the iPad's multitasking capabilities. It was introduced as iPadOS 13 in 2019, reflecting its status as the successor to iOS 12 for the iPad, at the company's 2019 Worldwide Developers Conference. iPadOS was released to the public on September 24, 2019. The current public release is iPadOS 16.2, released on December 13, 2022. History The first iPad was released on January 10th, 2010 and ran iPhone OS 3.2, which added support for the larger device to the operating system, previously only used on the iPhone and its smaller counterpart, the iPod Touch. This shared operating system was rebranded as "iOS" with the release of iOS 4. The operating system initially had rough feature parity running on the iPhone, iPod To ...

All Writs Act
The All Writs Act is a United States federal statute, codified at , which authorizes the United States federal courts to "issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law." The act in its original form was part of the Judiciary Act of 1789. The current form of the act was first passed in 1911 and the act has been amended several times since then, but it has not changed significantly in substance since 1789. Act The text of the Act is: Conditions for use Application of the All Writs Act requires the fulfillment of four conditions: * The absence of alternative remedies—the act is only applicable when other judicial tools are not available. * An independent basis for jurisdiction—the act authorizes writs in aid of jurisdiction, but does not in itself create any federal subject-matter jurisdiction. * Necessary or appropriate in aid of jurisdiction—the writ must be necessary or appropriate t ...

IPhone 5C
The iPhone 5C (marketed as iPhone 5c) is a smartphone that was designed and marketed by Apple Inc. It is part of the sixth generation of the iPhone. The device was unveiled on September 10, 2013, and released on September 20, 2013, along with its higher-end counterpart, the iPhone 5S. The "c" in the iPhone 5c's name stands for Color. The iPhone 5C is a variant of the iPhone 5, with similar hardware specifications but a hard-coated polycarbonate shell instead of the aluminum of the original iPhone 5. The iPhone 5C was available in several color options and shipped with iOS 7. The iPhone 5C was released at a lower price point than the new flagship 5S; unlike Apple's usual practice of lowering the price of the previous model upon release of a new version, the iPhone 5 was explicitly discontinued and replaced by the 5C. On September 9, 2014, the 16 and 32 GB iPhone 5C models were replaced by the 8 GB model upon the announcement of the iPhone 6 and 6 Plus. On S ...

2015 San Bernardino Attack
On December 2, 2015, a terrorist attack, consisting of a mass shooting and an attempted bombing, occurred at the Inland Regional Center in San Bernardino, California. The perpetrators, Syed Rizwan Farook and Tashfeen Malik, a married couple living in the city of Redlands, targeted a San Bernardino County Department of Public Health training event and Christmas party of about 80 employees in a rented banquet room. 14 people were killed and 22 others were seriously injured. Farook was a U.S.-born citizen of Pakistani descent, who worked as a health department employee. Malik was a Pakistani-born green card holder. After the shooting, the couple fled in a rented Ford Expedition SUV. Four hours later, police pursued their vehicle and killed them in a shootout, which also left two officers injured.

Bootloader
A bootloader, also spelled as boot loader or called boot manager and bootstrap loader, is a computer program that is responsible for booting a computer. When a computer is turned off, its softwareincluding operating systems, application code, and dataremains stored on non-volatile memory. When the computer is powered on, it typically does not have an operating system or its loader in random-access memory (RAM). The computer first executes a relatively small program stored in read-only memory (ROM, and later EEPROM, NOR flash) along with some needed data, to initialize RAM (especially on x86 systems), to access the nonvolatile device (usually block device, eg NAND flash) or devices from which the operating system programs and data can be loaded into RAM. Some earlier computer systems, upon receiving a boot signal from a human operator or a peripheral device, may load a very small number of fixed instructions into memory at a specific location, initialize at least one CPU, and the ...

Advanced Encryption Standard
The Advanced Encryption Standard (AES), also known by its original name Rijndael (), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. AES is a variant of the Rijndael block cipher developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits. AES has been adopted by the U.S. government. It supersedes the Data Encryption Standard (DES), which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data. In the United States, AES was announced by the NIST as U.S. FIPS PUB 197 (FIPS 197) on Novemb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SHA-2
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are novel hash functions computed with eight 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds. SHA-224 and SHA-384 are truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values. SHA-512/224 and SHA-512/256 are also trunca ...
