webcrypto library Null safety
Cryptographic primitives for use on Dart VM and Dart in the browser.
TODO: Finish documentation of a public identifiers, so far the folliwng items have been documented:
Exceptions
This library will throw the following exceptions:
- FormatException, if input data could not be parsed.
Errors
This library will throw the following errors:
- ArgumentError, when an parameter is out of range,
- UnsupportedError, when an operation isn't supported,
- OperationError, when an operation fails operation specific reason, this typically when the underlying cryptographic library returns an error.
Mapping Web Crypto Error
SyntaxErrorbecomes ArgumentError,QuotaExceededErrorbecomes ArgumentError,NotSupportedErrorbecomes UnsupportedError,DataErrorbecomes FormatException,OperationErrorbecomes OperationError,InvalidAccessErrorshouldn't occur, except for ECDH key derivation with mismatching curves where it becomes an ArgumentError.
