Expand description

Argon2 primitive type: variants of the algorithm.

Variants§

§

Argon2d

Optimizes against GPU cracking attacks but vulnerable to side-channels.

Accesses the memory array in a password dependent order, reducing the possibility of time–memory tradeoff (TMTO) attacks.

§

Argon2i

Optimized to resist side-channel attacks.

Accesses the memory array in a password independent order, increasing the possibility of time-memory tradeoff (TMTO) attacks.

§

Argon2id

Hybrid that mixes Argon2i and Argon2d passes (default).

Uses the Argon2i approach for the first half pass over memory and Argon2d approach for subsequent passes. This effectively places it in the “middle” between the other two: it doesn’t provide as good TMTO/GPU cracking resistance as Argon2d, nor as good of side-channel resistance as Argon2i, but overall provides the most well-rounded approach to both classes of attacks.
