Paying off technical debt
Every successful development team has two things in common: They’ve shipped a product, and they accepted compromises to make that shipment possible.

Cryptopals: Set 1 – challenge 5
Breaking encryption is fun. Building an encryption cipher is even more so! Let’s continue our Cryptopals journey with XOR.
-
Cryptopals: Set 1 – challenge 4
Now that we know how to crack a single-byte XOR cipher, let’s expand and crack even more through Cryptopals’ next challenge.
-
Cryptopals: Set 1 – challenge 3
Next up in our Cryptopals walkthrough is some frequency analysis against simple cryptographic keys. Let’s have some fun!
-
Cryptopals: Set 1 – challenge 2
Building on our cryptopals encoding work last time, let’s introduce byte-based XOR operations.
-
Cryptopals: Set 1 – challenge 1
Challenge 1 in the cryptopals suite is to juggle between Base64 and Hex encoding of byte strings. Let’s do just that, with value objects!

The Cryptopals challenges
Starting today I kick off a series on the cryptopals crypto challenges, with my implementations in PHP. Feel free to join in the fun!

One perspective on career stages
Different people see career progression from their own angles. I’ve encountered one that makes sense, tho I don’t so much see it as a progression.

Do the dishes – right now
Refactoring legacy code is like cleaning the dishes. Someone has to do it – hopefully before the stack of moldering waste falls on the floor.

The value of encryption
I care very deeply about privacy, which translates to a passion for encryption and cryptography. You should care about privacy, too.
