1C HMAC & JWT

This is a pure 1C implementation of RFC 2104 https://www.ietf.org/rfc/rfc2104.txt and RFC 7519 https://tools.ietf.org/html/rfc7519

Limitations

This implementation works only on 1C:Enterprise platform version 8.3.10.2168 or above.
The platform you may download here: https://1c-dn.com/user/updates/1c_enterprise_platform_training_version/
For JWT supported algorithm HS256 only.
HMAC function supports algorithms: MD5, SHA1, SHA256

PS: Since version 8.3.21 you may use AccessToken object to create JWT.

Installing

Download modules Cryptography.bsl and JWT.bsl. Put modules into the 1C application.

Usage

	
	// HMAC
	SecretKey = "key";
	StringToSign = "The quick brown fox jumps over the lazy dog";
	Signature = Cryptography.HMAC(
		GetBinaryDataFromString(SecretKey),
		GetBinaryDataFromString(StringToSign),
		HashFunction.SHA256);

	// JWT
	SecretKey = "secret";
	Payload = New Structure;
	Payload.Insert("sub", "1234567890");
	Payload.Insert("name", "John Doe");
	Payload.Insert("admin", True);
	
	Token = JWT.Encode(SecretKey, Payload);
	
	DecodedPayload = JWT.Decode(Token, SecretKey);
