ID & Hash Generator API
The ID & Hash Generator API is a lightweight, high-performance REST API that provides developers with everything needed to generate secure identifiers and cryptographic hashes.
Instead of maintaining multiple libraries for hashing and ID generation, developers can use one simple API to create UUIDs, NanoIDs, and secure hashes using industry-standard algorithms.
This API is suitable for authentication systems, distributed services, databases, API keys, invitation codes, URL shorteners, IoT platforms, event processing, blockchain applications, logging systems, and countless other use cases.
All generated IDs use cryptographically secure random sources where applicable, making them suitable for production environments.

Parameters
| Name | Type | Required | Description |
|---|
| text | string | Yes | Text to hash |
| algorithm | string | No | md5, sha1, sha256, sha512 |
Generate NanoIDs
GET
/nanoid
Generate secure URL-safe NanoIDs.
Parameters
| Name | Type | Required | Description |
|---|

Generate UUID v4
GET
/uuid
Generate one or more Version 4 UUIDs.
Parameters
| Name | Type | Required | Description |
|---|
| count | integer | No | Number of UUIDs |
Parameters
text
The string to hash.
Example
hello world
algorithm
Supported values
md5
sha1
sha256
sha512
Default recommendation:
sha256
count
Number of identifiers to generate.
Example
10
size
NanoID length.
Example
21
Longer IDs provide greater uniqueness.
Example Requests
Generate SHA-256 hash
GET /hash?text=HelloWorld&algorithm=sha256
Generate NanoIDs
GET /nanoid?count=5&size=21
Generate UUIDs
GET /uuid?count=10

Best Practices
- Use SHA-256 or SHA-512 for new applications.
- Avoid MD5 and SHA-1 for security-sensitive data.
- Use UUID v4 for globally unique identifiers.
- Use NanoIDs for short, URL-friendly public IDs.
- Increase NanoID size when generating very large numbers of identifiers.
