Tools
Use the built-in utilities for common testing tasks without leaving your workspace. Convert data, generate hashes, scan authorized hosts, copy results, and export findings as you work.
Encoder/Decoder
Convert URL, Base64, and Hex values while reviewing parameters, tokens, or payloads.
Hash Generator
Generate common hashes from text so you can compare values during analysis.
Port Scanner
Check which TCP services are reachable on hosts you are authorized to assess.
Encoder / Decoder
Use Encoder / Decoder when a request contains encoded values or when you need to prepare a value for a test. Paste input, choose the format, choose encode or decode, then copy the output.
| Format | Encode | Decode |
|---|---|---|
| URL | Prepare text for a query string or form value. | Read encoded URL parameters. |
| Base64 | Turn readable text into Base64. | Decode Base64 tokens, blobs, or copied values. |
| Hex | Turn readable text into hexadecimal. | Decode hexadecimal strings into readable text. |
Swap
Move the output back into the input field and switch direction for quick round trips.
Copy
Copies the output to clipboard.
Clear
Clears both input and output fields.
Invalid Input
If a value cannot be decoded, fix the input and try again instead of trusting partial output.
Hash Generator
Use Hash Generator when you need to compare a value with a known hash, check whether two strings produce the same digest, or document a stable fingerprint for a finding. Choose an algorithm, paste text, then copy the generated hash.
| Algorithm | Method |
|---|---|
| MD5 | Legacy checksums and older application behavior. |
| SHA-1 | Legacy fingerprints and compatibility checks. |
| SHA-224 | Shorter SHA-2 digest needs. |
| SHA-256 | General-purpose comparisons and the recommended default. |
| SHA-384 | Longer SHA-2 digest needs. |
| SHA-512 | High-length SHA-2 digest comparisons. |
| SHA3-224 | Shorter SHA-3 digest needs. |
| SHA3-256 | Modern SHA-3 comparisons. |
| SHA3-384 | Longer SHA-3 digest needs. |
| SHA3-512 | High-length SHA-3 digest comparisons. |
| RIPEMD-160 | Compatibility checks for systems that use RIPEMD-160. |
The hash updates as you type or change the selected algorithm. Use copy when you need to paste the result into a note, report, or another 0xbuffer workflow.
Port Scanner
Use Port Scanner to check reachable TCP services on systems you are authorized to assess. Start with a quick or web preset, then expand only when the test scope allows it.
Port Presets
| Preset | Ports |
|---|---|
| Quick | A small set of common service ports for fast orientation. |
| Web | Common HTTP and HTTPS ports for web application testing. |
| Top 100 | A broader scan of common TCP services. |
| Full | All TCP ports. Use only when authorized and when the target can handle it. |
| Custom | A range or list you define for the current test scope. |
Real-time Progress
Watch scan progress and review open ports as they appear.
Cancellable
Stop a scan at any time if the target is out of scope, too noisy, or no longer needed.
Copy Open Ports
Copy host:port pairs for notes, follow-up testing, or another tool.
Export
Download results as JSON or CSV so you can keep evidence with your recon notes.
Configuration
Target
Hostname, IP address, or in-scope network range.
Timeout
How long to wait for each port before treating it as closed or unavailable.
Concurrency
How many ports to check at once. Lower it for fragile or sensitive targets.
Banner Grab
Try to capture service banners from open ports for easier identification.
Safe Usage
Only scan hosts and networks you own or have permission to assess. Use narrower presets first, keep concurrency reasonable, and export results before clearing or moving to the next target.
