PBKDF2-HMAC-SHA256

[philsmd]

it's written in the document you linked: https://perlmaven.com/storing-passwords-...secure-way -> https://metacpan.org/pod/Crypt::PBKDF2 -> "the number of iterations encoded with MIME::Base64"

Code:

$ echo AAAD6A== | base64 -d | xxd -p
000003e8

0x03e8 (hex) == 1000 (dec)

---

or just use a perl script:

Code:

perl -MMIME::Base64 -e 'print unpack ("L>", decode_base64 ("AAAD6A")) . "\n"'
1000
