Decode Base64

What it can do

• Decode the standard Base64 alphabet
• Ignore whitespace safely
• Feed the recovered bytes into additional operations

Recipe

From Base64 → output

Demonstration

Input:

U28gbG9uZyBhbmQgdGhhbmtzIGZvciBhbGwgdGhlIGZpc2gu

Expected output:

So long and thanks for all the fish.

Extend it

Add JSON Beautify for API payloads, Gunzip for a compressed wrapper, or To Hex when the decoded result is binary. Verify the bytes before assuming the next layer.
