SHA512 Hash Generator

Generate SHA512 hashes from text strings or files. Fast, reliable, and secure for data integrity verification and cryptographic fingerprinting.

What does SHA512 Hash Generator do?

SHA512 Hash Generator creates SHA512 cryptographic hashes from your input data. You can hash plain text strings or files from any URL. The actor processes multiple items in a single run and outputs the hash for each item.

• Text Hashing: Hash any plain text string directly
• File Hashing: Hash files from any URL (direct download links)
• Batch Processing: Process multiple items in a single run
• Detailed Output: Get hash, input size, and processing timestamp for each item

Use Cases

• Data Integrity: Verify file integrity by comparing SHA512 checksums
• Deduplication: Identify duplicate content by comparing hashes
• Security Applications: Generate secure hashes for authentication and verification
• File Fingerprinting: Create unique identifiers for files
• Content Verification: Ensure data hasn't been modified

Input

Field	Type	Required	Description
textInputs	array	No	List of text strings to hash
fileUrls	array	No	List of file URLs to download and hash (supports advanced HTTP options)

Example Input (Simple)

{
    "textInputs": ["Hello World", "Another string to hash"],
    "fileUrls": [
        { "url": "https://example.com/file.txt" }
    ]
}

Advanced File URL Options

The fileUrls field supports full HTTP request configuration for each URL:

Property	Type	Required	Description
url	string	Yes	The URL to fetch
method	string	No	HTTP method (GET, POST, PUT, etc.). Default: GET
headers	object	No	Custom HTTP headers to send with the request
payload	string	No	Request body for POST/PUT requests
userData	object	No	Custom data passed through for your reference

Example Input (Advanced)

{
    "textInputs": ["Hello World"],
    "fileUrls": [
        { "url": "https://example.com/public-file.txt" },
        {
            "url": "https://api.example.com/protected-file",
            "method": "GET",
            "headers": {
                "Authorization": "Bearer your-token-here",
                "X-Custom-Header": "custom-value"
            }
        },
        {
            "url": "https://api.example.com/generate-data",
            "method": "POST",
            "payload": "{\"format\": \"json\"}",
            "headers": {
                "Content-Type": "application/json"
            }
        }
    ]
}

Output

Each processed item produces a dataset record with:

Field	Description
input	The original input (text preview or file URL)
inputType	Type of input: "text" or "file"
sha512Hash	The 128-character SHA512 hash in lowercase hex
inputSizeBytes	Size of input data in bytes
processedAt	ISO timestamp of when hash was generated
error	Error message if processing failed, null otherwise

Example Output

{
    "input": "Hello World",
    "inputType": "text",
    "sha512Hash": "2c74fd17edafd80e8447b0d46741ee243b7eb74dd2149a0ab1b9246fb30382f27e853d8585719e0e67cbda0daa8f51671064615d645ae27acb15bfb1447f459b",
    "inputSizeBytes": 11,
    "processedAt": "2024-01-15T10:30:00.000Z",
    "error": null
}

Pricing

This actor uses pay-per-event pricing:

Event	Price	Description
Text Processed	$0.0001	Charged for each text string hashed
File Processed	$0.0002	Charged for each file fetched and hashed

Example costs:

• 1,000 text items: $0.10
• 1,000 file items: $0.20
• Mixed 500 text + 500 files: $0.15

Integrations

Works with all Apify integrations:

FAQ

Q: What's the difference between SHA512 and MD5? A: SHA512 produces a 128-character hash (512 bits) compared to MD5's 32-character hash (128 bits). SHA512 is cryptographically stronger and recommended for security-sensitive applications.

Q: Is SHA512 secure for passwords? A: While SHA512 is more secure than MD5, for password hashing you should use specialized algorithms like bcrypt or Argon2 that include salting and key stretching.

Q: What's the maximum file size? A: Files are limited by available memory. The actor uses 128-256 MB, supporting files up to ~200 MB.

Q: Can I hash files from any URL? A: Yes! Any publicly accessible URL is supported. The file will be downloaded and hashed.

Q: What format is the hash output? A: Hashes are returned as 128-character lowercase hexadecimal strings.
