Merge 'Cryptography' category into 'Encryption'

[dimssu]

Fixes #2822

The 'Cryptography' and 'Encryption' blog categories were equivalent and redundant. This commit merges them by changing the remaining blog post using 'Cryptography' to use 'Encryption' instead.

What is your reasoning for choosing Encryption as winner?

What is your reasoning for choosing Encryption as winner?

@HarHarLinks Below are the main factors that influenced the decision to go with "Encryption."

• "Encryption" is more user-friendly than the technical term "Cryptography"
• Content focus: Both posts discuss practical encryption implementations, not cryptographic theory
• Better discoverability: Users searching for "how to secure messages" think "encryption" not "cryptography"
• Matches Matrix's mission: Making secure communications accessible requires accessible terminology
• Semantic accuracy: Posts are about encryption systems (libolm, vodozemac, MLS), not the broader field of cryptography
• Consistency with existing categories: Blog uses outcome-oriented terms like "Security," "Trust & Safety," "Tech"
• User expectations: /category/encryption immediately conveys "secure communications"

@HarHarLinks Should I take the opposite approach and merge Encryption into Cryptography instead?

[HarHarLinks]

Thank you, sorry for taking a bit of time to come back to this.

My initial tendency was the opposite, but I find the argument to use simple terms convincing. Particularly, we usually speak about "end to end encryption", so it would make sense to generalise on "encryption".

There was a new blog post added to cryptography in the meantime. Could you update the PR to also include that one?

@HarHarLinks I've updated the category of the newly added blog as well
