इस रेसिपी का उपयोग कब करें

Prepare sensitive data for secure API transport with integrity verification and authentication. Used in payment APIs, banking integrations, and inter-service communication.

चरण

1

Validate data structure

प्रॉम्प्ट:Validate and format the JSON payload before encoding: {"userId": 123, "action": "transfer", "amount": 500}
2

Encode for transport

प्रॉम्प्ट:Base64 encode the validated JSON payload for safe HTTP transport
3

Create content digest

प्रॉम्प्ट:Generate SHA-256 hash of the original JSON as a content digest
4

Sign the encoded payload

प्रॉम्प्ट:Generate HMAC-SHA256 of the Base64 payload for authenticated verification

अक्सर पूछे जाने वाले प्रश्न

Why Base64 encode before HMAC?

Base64 provides a canonical text representation. HMACing the Base64 form means both sender and receiver compute the signature on the exact same byte sequence.

Is Base64 encryption?

No. Base64 is encoding, not encryption. It converts binary to text for transport but provides zero confidentiality. Anyone can decode it. Use AES for encryption.
