View Git Tags with Semver Ordering

What is semver

The post View Git Tags with Semver Ordering first appeared on Qvault.

If you’re like me, you wish all Git tags adhered to the Semantic Versioning standard. Unfortunately, Semver is just a convention, so Git tags can basically be any string of text. By default when you use the git tag command, your output will be in alphabetical order. Being a gopher, almost all the projects I work on are tagged according to Semver standards, which means the default output is fairly useless.

In order to print all the Git tags in a project in Semver order, simply run git tag -l | sort -V.

Alternatively, if you’re on at least version 2 of Git, you won’t even need to use the sort command, just run:

git tag -l --sort=version:refname

If you want the latest tags at the top of the output, use -version to inverse the sort:

git tag -l --sort=-version:refname

If you want your global installation of Git to default to Semver sorting, you can use the following command as of Git v2.1+:

git config --global tag.sort version:refname

Examples of Git standard output

Why is Exclusive Or (XOR) Important in Cryptography?

Image
If you are getting into cryptography, or just trying to understand the fundamentals, you may have noticed that the exclusive-or operation is used quite often, especially in ciphers. What is XOR ( ⊕ )? XOR, or “exclusive or” operates on binary data. It returns true if both of its inputs are opposites (one false and one true), otherwise, it returns false. An example in go code would be something like: func exclusiveOr(a bool, b bool) bool { return a != b } XOR Cipher – The Perfect Cipher The XOR operation can be used as a simple cipher for encrypting and decrypting messages with a single key. This is known as symmetric encryption. It is interesting to note that if: The key is the same size as the message The key is kept secret and generated truly randomly Then the cipher is impossible to crack. This is known as a one time pad . However, a simple XOR shouldn’t be used in production due to the key length needing to be too long to be practical. Cipher Example A...

Base64 vs Base58 Encoding

Image
By Lane Wagner –  @wagslane  on Twitter Base64 is one of the most popular encoding formats for representing data. Have some binary data? Base64 encode it for convenient readability and parsing. Base58 is just another encoding format (with 58 characters instead of 64, and has gained popularity largely due to Bitcoin and other cryptocurrencies. When it comes to data encoding, there is typically a trade-off made between: Human Readability: Do humans have a good idea of what is being represented at a glance? Efficient data compression: How many bytes are used to represent the same data? Let’s rank Base58, Base64, and ASCII encoding against each other using these metrics! First: A Note on Binary All data is stored in a raw binary format on computers. These encoding formats (Base64, Base58, and ASCII) are just different ways of reading and writing binary data. For example, in Base64 the binary code 000000 represents the letter A , but in ASCII the binary 00000000 repres...

(Very) Basic Intro to Hash Functions (SHA-256, MD-5, etc)

Image
This is going to be a basic introduction to hash functions. I will assume most of my audience is here to gain an understanding of why hash functions are used and the basic idea of why they work. My goal is to explain it in a general sense, I will be omitting proofs and implementation details and instead focusing on the high-level principles. Why Use A Hash Function? Hash functions are used all over the internet in order to securely store passwords, find duplicate records, quickly store and retrieve data, and more. For example,  Qvault  uses hashes to extend master passwords into private encryption keys. A longer list of uses here:  https://en.wikipedia.org/wiki/Hash_function#Uses I want to focus on several important features of hash functions, arguably the most important features. Hash functions scramble data deterministically No matter the input, the output of a hash function always has the same size The original data can not be retrieved from the scrambled d...
