Verify ECDSA Signature
Verifies a digital signature against the specified Elliptic Curve Digital Signature Algorithm (ECDSA) public key.
In the diagram below, the dark rectangle represents the activity of verifying a signature against some data using a public key that is retrieved from the server which signed the data.
Also see: Create ECDSA Keys, Generate ECDSA Signature.
Properties
Section titled “Properties”Public key
Section titled “Public key”The public ECDSA key against which to verify the signature (see Create ECDSA Keys). The public ECDSA key against which to verify the signature (see Create ECDSA Keys).
The key can be given as a list of bytes or a base64 string.
Hash algorithm
Section titled “Hash algorithm”The hash algorithm that was used to sign the data.
Options:
- SHA256 - learn more
- SHA384 - learn more
- SHA512 - learn more
The data against which to verify the signature. This can be a list of bytes or a base64 string.
Signature
Section titled “Signature”The signed data to verify (see Generate ECDSA Signature). This can be a list of bytes or a base64 string. The signed data to verify (see Generate ECDSA Signature). This can be a list of bytes or a base64 string.
Definition
Section titled “Definition”A boolean value (true / false) indicating if the specified signature is valid given the public key and data. A boolean value (true / false) indicating if the specified signature is valid given the public key and data.
