1. The request "convert it to ECDSA signature" refers to a cryptographic operation, not a mathematical problem that involves calculations or algebraic manipulation. 2. ECDSA (Elliptic Curve Digital Signature Algorithm) involves generating a digital signature for data using elliptic curve cryptography. 3. This process requires a private key, a message hash, and involves elliptic curve point multiplication and modular arithmetic rather than symbolic math or algebra. 4. Since your request is about cryptographic signature generation, it doesn't fit the typical math problem format with steps and formulas to show directly here. 5. If you need to implement ECDSA signature generation, typically you'd use a cryptographic library in a programming language, providing the message and private key to get the signature. 6. If you want to understand the math behind ECDSA signatures, it involves elliptic curve point operations and modular inverses, which can be explained separately if you specify that.
