Checksum

About

+
+ +
+

+ Files get corrupted and malicious actors tamper with files. + There are many things that can go wrong when transfering files between two parties. + Checksums and signatures are provided to help protect against these kinds of problems. +

+
+
+ +
+
+

SHA2

+
+ +
+

+ The checksum algorithm known as SHA2 is utilized as a quick and simple integrity check on files. + This also functions as a poor mans authentication but offers no real security that the checksum itself is valid. + The GPG checksums are a more appropriate choice for authentication. +

+

+ There are several variations of this algorithm. +

+
    +
  1. SHA512: A 512-byte version of SHA2 that results the largest, strongest, and slowest checksums. +
  2. SHA385: A 384-byte version of SHA2. +
  3. SHA256: A 256-byte version of SHA2. +
  4. SHA224: A 224-byte version of SHA2 that results in the smallest, weakest, and fastest checksums. +
+
+
+ +
+
+

GPG / PGP

+
+ +
+

+ The GPG is an open-source implementation, or perhaps version, of the PGP standard. + This provides signatures and even encryption of files that are often called keys. + There are several different forms of security and data integrity. + Within the GPG key, checksums algorithms like SHA2 are also used. +

+

+ There are public and private parts to a GPG key. + The public part of a GPG key is given out publically so that the person receiving the files can verify the integrity and authenticity of the files. + These keys are even used to verify and encrypt e-mails. +

+

+ The following are public keys from Kevin Day and are themselves signed and checksumed. +

+
    +
  1. 2024 and earlier: Kevin Day 76E903396DAD0A83 (SHA256) (GPG).
    2. +
  2. 2023 and later: Kevin Day 02E939B8F7EFE597 (SHA256) (GPG).
    3. +
+

+ The key identified by 76E903396DAD0A83 is authenticated via the key identified by 02E939B8F7EFE597. + This key will expire near the start of 2024 and will not be used again. + This followed the old, and perhaps lazy, practice of using the master key for signing everything. + This also utilizes older and less trusted algorithms. +

+

+ The key identified by 02E939B8F7EFE597 is authenticated via the key identified by 76E903396DAD0A83. + This key has been created near the start of 2023 and will be used until such time a replacement comes about. + This follows the newer practice of signing using subkeys, making the master key unavailable. + This key utilizes newer algorithms. +

+

+ These public keys should be downloaded imported into your own key chain to perform integrity checking and authentication. +
