HashCrack can detect and crack the following hash types:
| Hash Type | Description | Example/Format |
|---|---|---|

| SHA1 | 40 characters, hexadecimal | 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8 |
| SHA224 | 56 characters, hexadecimal | d14a028c2a3a2bc9476102bb288234c415a2b01f828ea62ac5b3e42f |
| SHA256 | 64 characters, hexadecimal | 5e884898da28047151d0e56f8dc6292773603d0d6aabbdd62a11ef721d1542d8 |

| SHA512 | 128 characters, hexadecimal | b109f3bbbc244eb82441917ed06d618b9008dd09b3befd1b5e07394c706a8bb980b1d7785e5976ec049b46df5f1326af5a2ea6d103fd07c95385ffab0cacbc86 |
| MD5 Crypt | Starts with $1$ |
$1$salt$hash |
| bcrypt | Starts with $2a$ or $2b$ |
$2a$10$salt_and_hash |
| SHA-256 Crypt | Starts with $5$ |
$5$salt$hash |
| SHA-512 Crypt | Starts with $6$ |
$6$salt$hash |
| NTLM | 32 characters | 8846F7EAEE8FB117AD06BDD830B7586C |
| MySQL-SHA1 | Format: *<40 HEX CHARS> |
*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19 |
| PBKDF2 | Format varies with implementation | $pbkdf2$iterations$salt$hash |
| yescrypt | Modern password hashing | $y$params$salt$hash |
| Argon2 | Winner of PHC competition | $argon2id$v=19$m=65536,t=3,p=4$salt$hash |
| scrypt | Memory-hard hashing function | $scrypt$params$salt$hash |
| NetNTLMv2 | Windows authentication | hash:challenge |
| WPA-PMKID | WiFi password hashing | pmkid*mac1*mac2 |
The following hash types are also supported but may be slower in browser environments:
| Hash Type | Description | Format Example |
|---|---|---|
| KeePass KDBX | Password manager format | kdbx:<version>:<iterations>:<salt_base64>:<header_hash> |
| 7z | Archive format | 7z:<salt_hex>:<iterations>:<chash> |
| RAR5 | Archive format | rar5:<iterations>:<salt_hex>:<checkval_hex> |
| Document encryption | pdf:<version>:<algorithm>:<iterations>:<salt_hex>:<u_hex>:<o_hex> |
Note: For the memory-hard functions (Argon2, scrypt, yescrypt) and algorithms requiring specific libraries (bcrypt), we use high-iteration PBKDF2 as a fallback in browser environments where external modules may not be fully supported. This approach provides compatibility while maintaining reasonable security approximation.
