Package: argon2 Version: 0~20160406-2 When argon2(1) is executed, it always produces an unsuccessful exit with exit code 132, and the error message `Illegal instruction', regardless of options passed. The expected password hash is never printed to STDOUT.
For example:
$ echo password | argon2 deadbeef
Type: Argon2i
Iterations: 3
Memory: 4096 KiB
Parallelism: 1
Illegal instruction
$ echo $?
132
$ echo password | argon2 deadbeef -t 4069 -m 13 -p 4
Type: Argon2i
Iterations: 4069
Memory: 8192 KiB
Parallelism: 4
Illegal instruction
$ echo $?
132
Changing the salt length doesn't change anything:
$ echo password | argon2 ca5cadedbeefcafe
Type: Argon2i
Iterations: 3
Memory: 4096 KiB
Parallelism: 1
Illegal instruction
$ echo $?
132
Executing with strace(1) to get more information:
$ echo password | strace -f argon2 deadbeef

Description: memory-hard hashing function - utility
Argon2 is a password-hashing function that can be used to hash passwords
for credential storage, key derivation, or other applications.
.
There are two main versions of Argon2: Argon2i and Argon2d.
Argon2i is the safest against side-channel attacks, while Argon2d provides
the highest resistance against GPU cracking attacks.
.
Argon2i and Argon2d are parametrized by:
* A time cost, which defines the amount of computation realized and
therefore the execution time, given in number of iterations
* A memory cost, which defines the memory usage, given in kibibytes
* A parallelism degree, which defines the number of parallel threads
.
This package contains the argon2 tool for hashing data on the command-line.
