// Algorithm based on documented client behavior:
|
|
// - Remap digits using pinGridSeed (a permutation of 0..9)
|
|
// - Convert user-entered PIN digits into randomized indices in that permutation
|
|
// - Compute: pin_hash = SHA1(client_salt || SHA1(server_salt || randomized_pin_ascii))
|
|
//
|
|
// PIN must be 4-10 ASCII digits.
