How is 'ECDSA' (Elliptic Curve Digital Signature Algorithm) pronounced?
ECDSA is pronounced as an initialism: /iː siː diː ɛs eɪ/ — 'ee see dee es ay', spelling out each letter. This is the universal convention for cryptographic algorithm abbreviations. Options B and C invent blended syllables not used in the security community; option D only gives the partial expansion.
2 / 5
How is 'ChaCha20' (stream cipher) pronounced?
ChaCha20 is pronounced /ˈtʃɑːtʃɑː ˈtwɛnti/ — 'CHA-cha TWEN-tee', like the Latin dance 'cha-cha' with stress on the first syllable of each word. The cipher was named with this playful pronunciation in mind by Daniel Bernstein. Option B uses /ʃ/ instead of /tʃ/; option C shifts stress; option D entirely changes the first syllable.
3 / 5
How is 'Argon2' (password hashing function) pronounced?
Argon2 is pronounced /ˈɑːrɡɒn tuː/ — 'AR-gon two'. It is named after argon (the noble gas), pronounced identically: stress on the first syllable, short /ɒ/ vowel in 'gon'. Option B shifts stress to the second syllable; option C is nearly identical but uses the non-standard /tʊ/; option D reorders the consonants.
4 / 5
How is 'bcrypt' (password hashing function) pronounced?
Bcrypt is pronounced /biː krɪpt/ — 'BEE kript'. The 'b' is the letter name /biː/, and 'crypt' is the standard English word /krɪpt/. The 'b' prefix indicates the Blowfish cipher family. Options B and D incorrectly stress the second syllable; option C drops the 'p' from 'crypt'.
5 / 5
How is 'Ed25519' (elliptic curve signature scheme) pronounced?
Ed25519 is pronounced /ɛd tuː faɪv faɪv wʌn naɪn/ — 'ED two five five one nine', reading each digit individually. 'Ed' refers to Edwards-curve, and the number identifies the curve parameters. Security professionals consistently read the digits one by one. Options B, C, and D misread the digits or invent syllables.
