Is an Apache md5apr1 ($apr1$) hash reversible?

No. Apache md5apr1 ($apr1$) is a one-way hash; you cannot reverse it. You can only guess inputs and compare, which is what hashcat and John do.

What is the hashcat mode for Apache md5apr1 ($apr1$)?

Use `-m 1600` to tell hashcat to treat the input as Apache md5apr1 ($apr1$).

How long does it take to crack Apache md5apr1 ($apr1$)?

Apache md5apr1 ($apr1$) is fast to compute, so weak passwords often fall in seconds to minutes on a GPU; strong, long passwords remain infeasible.

How to identify and crack an Apache md5apr1 ($apr1$) hash

Apache md5apr1 ($apr1$) is an application hash type. It is fast and typically unsalted, which makes weak passwords recoverable quickly on consumer GPU hardware. This page shows how to recognise it and the exact commands to attack it.

All identification runs locally in WebAssembly. The commands below write the hash to a local file on your machine — nothing is sent to this site.

Identifying the hash

The hash identifier on the home page detects Apache md5apr1 ($apr1$) entirely in your browser — your hash is never uploaded. A typical example looks like this:

$apr1$71850310$gh9m4xcAn3MGxogwX/ztb.

Cracking Apache md5apr1 ($apr1$) with hashcat

Save the hash to a file and run hashcat in mode -m 1600. Start with a wordlist such as rockyou.txt:

echo '$apr1$71850310$gh9m4xcAn3MGxogwX/ztb.' > hash.txt && hashcat -m 1600 hash.txt /usr/share/wordlists/rockyou.txt

Add a rule set to mutate dictionary words (capitalisation, leetspeak, appended digits) and dramatically widen coverage:

echo '$apr1$71850310$gh9m4xcAn3MGxogwX/ztb.' > hash.txt && hashcat -m 1600 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

Cracking Apache md5apr1 ($apr1$) with John the Ripper

John the Ripper can attack the same hash with the md5crypt format:

echo '$apr1$71850310$gh9m4xcAn3MGxogwX/ztb.' > hash.txt && john --format=md5crypt --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
