What is Argon2d?

Argon2d is a variant of the Argon2 cryptographic hashing algorithm. Argon2 is a key derivation function that was selected as the winner of the Password Hashing Competition in July 2015. Argon2d maximizes resistance to GPU cracking attacks.It accesses the memory array in a password dependent order, which reduces the possibility of time memory trade-off aka (TMTO) attacks, but introduces possible side-channel attacks.
