Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN commenters link the author's writing on WTF-8, a UTF-8 extension for bridging with UCS-2 and surrogate-based systems, and a 2011 post on hashing passwords with pbkdf2. Comments cite them as sources.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionLooks to me like the $ signs are acting as delimiters, and that that hash is made up of: cipher/hash: pbkdf2_sha256 cost factor: 12000 salt: zhMKabMgayvK hash: iniviUCcX9y2PYJcm0AoB3MhybRA1z2Cec1DZnLWxWc= This exact technique (pretty much) is described here: http://exyr.org/2011/hashing-passwords/ . It's a decent, secure way to hash passwords. Cost factor of 12000 seems solid to me (depends on the hardware they're r…
