Tool Introduction
NTLM Hash (New Technology LAN Manager Hash) is a password hashing algorithm widely used in Windows operating systems and their network services. This online tool aims to provide users with a fast and convenient NTLM hash calculation function. You only need to enter a plaintext, Hex, or Base64 encoded string, and select the desired output case format, to generate the corresponding NTLM hash value with one click, displayed in both Hex and Base64 common formats. Whether for security testing, password analysis, or system administration, this tool can provide you with efficient NTLM hash calculation services.
How to Use
- In the “String to be encrypted” text box, enter the original string for which you need to calculate the NTLM hash value.
- According to the actual format of your input string, select the corresponding option in the “Input Type” dropdown menu: “Plaintext”, “Hex”, or “Base64”. The tool defaults to “Plaintext” input.
- In the “Case” radio button group, select whether you want the final output NTLM hash value to be displayed in “Lowercase” or “Uppercase”.
- After completing the above settings, click the tool's “Calculate” or “Generate” button (the specific button name is subject to the page display) to view the generated NTLM hash value in the result area.
Input Parameter Format Requirements:
- String to be encrypted: This is a required field and supports input of any text characters.
- Input Type: If “Hex” is selected, please ensure that the input is a valid hexadecimal string; if “Base64” is selected, please ensure that the input is a valid Base64 encoded string. Selecting the correct input type is crucial for obtaining the correct hash result.
- Case: This option will control the case display of the final output Hex and Base64 format hash values.
Output Result Format:
The tool will clearly display the NTLM hash results in a list format, mainly including the following two columns:
- Hex: The hexadecimal string representation of the NTLM hash value.
- Base64: The Base64 encoded string representation of the NTLM hash value.
Usage Example
Example Input:
- String to be encrypted:
password
- Input Type:
Plaintext
- Case:
Lowercase
Expected Output Result:
| Hex |
Base64 |
| 8846f7eaee8fb117ad06bdd830b7586c |
iEb36u6PsRetB73YMIdYnA== |
Specific Operation Demonstration:
- Fill in
password in the “String to be encrypted” input box.
- Select
Plaintext for “Input Type”.
- Select
Lowercase for “Case”.
- Click the calculate button, and the NTLM hash values in Hex and Base64 formats mentioned above will be displayed at the bottom of the page.
Frequently Asked Questions
- Q: What scenarios is NTLM hash primarily used for?
- A: NTLM hash is primarily used for user authentication in Microsoft Windows operating systems, especially in earlier Windows versions and certain network protocols. It converts user passwords into hash values for storage and verification, preventing plaintext password disclosure.
- Q: What input formats does this tool support?
- A: This NTLM hash online tool supports three common input formats: plaintext, hexadecimal (Hex), and Base64 encoding. You can choose the appropriate input type according to your actual needs.
- Q: What format is the output NTLM hash value?
- A: The tool will provide both hexadecimal (Hex) and Base64 encoding formats for the NTLM hash value. Users can also choose the case of the output result.
- Q: How does NTLM hash differ from hash algorithms like MD5 and SHA-1?
- A: NTLM hash is a hash algorithm specific to the Windows authentication system. Its internal implementation differs from general hash algorithms like MD5 or SHA-1, and it is generally considered less secure than modern recommended hash algorithms (such as PBKDF2, bcrypt, etc.) because its design has limitations in resisting brute-force and rainbow table attacks.
Notes
- Please ensure that the content you enter in “String to be encrypted” is accurate. Any subtle difference will lead to a completely different hash result.
- It is crucial to correctly select the “Input Type”, as it directly affects how the tool parses the input string. For example, if you enter a Base64 encoded string but select “Plaintext”, the tool will calculate the hash of the Base64 string itself as plaintext, rather than its decoded content.
- NTLM hash is a relatively old hashing algorithm. In modern applications with higher security requirements, it is generally recommended to use stronger key derivation functions (such as PBKDF2, bcrypt, scrypt) to store and verify passwords to enhance resistance against cracking attacks. This tool is more suitable for compatibility testing, analysis, or educational purposes.
- This online tool only provides NTLM hash calculation functionality and does not store or record any sensitive information entered by users. Please feel free to use it.
