Static Value

Category: Input/Output Data · Node Type ID: input-static-value

Provides a constant value of a user-selected type (bytes/string/int/bool)

Overview

Provides a constant, deterministic value of a user-selected primitive data type (Bytes, String, Int, or Bool) into the workflow graph. When you change the Type parameter, both the visible value input field in the property inspector and the runtime type of the single Value output port adapt to match the selected type.

In Bytes mode, the hexadecimal string entered in Value (Bytes) is validated and decoded into a raw Uint8Array before execution. In Int mode, integer literals of arbitrary precision are parsed into a signed bigint, allowing 64-bit counters, RSA exponents, or large finite-field constants without JavaScript floating-point precision loss. All value fields also support binding to a workspace variable reference ($var) of the matching type.

When to Use

Supplying a known cryptographic key, initialization vector (IV), nonce, or test-vector message from a standard specification (such as NIST CAVP or RFC test vectors).
Feeding a constant integer (such as a slice offset, byte length, or bit-shift count) or boolean flag into downstream utility or script nodes.
Binding a single shared constant from the Variable Registry ($var) so multiple nodes in a workflow reference the same key or parameter.

Parameter Configuration

Parameter (ID)	Type & Default	Visibility Condition	Description & Options
Type `type`	`select` Default: `bytes`	Always visible	Selects the primitive data type emitted by the `Value` output port and determines which value editor field is shown below. `bytes`: Bytes (Hex) `string`: String (Text) `int`: Int (Number) `bool`: Bool (True/False)
Value (Bytes) `valueBytes`	`hex` Default: `00112233445566778899aabbccddeeff` Supports Variable Reference (`$var`: `bytes`)	When `type` is `bytes`	Hexadecimal byte string (even number of hex digits `0-9a-fA-F`; whitespace is ignored). Empty string produces a 0-byte `Uint8Array`.
Value (String) `valueString`	`textarea` Default: `Hello NodeCrypto!` Supports Variable Reference (`$var`: `string`)	When `type` is `string`	Literal UTF-8 text string emitted directly on the `Value` port when `Type = string`.
Value (Int) `valueInt`	`number` Default: `0` Supports Variable Reference (`$var`: `int`)	When `type` is `int`	Signed arbitrary-precision integer literal (parsed as `bigint`; defaults to `0` if blank) emitted when `Type = int`.
Value (Bool) `valueBool`	`select` Default: `false` Supports Variable Reference (`$var`: `bool`)	When `type` is `bool`	Boolean constant (`true` or `false`) emitted when `Type = bool`. `true`: True `false`: False

Input Ports

This node has no input ports.

Output Ports

Port Nature: Fixed Output Ports (1 total).

Port Name	Port ID	Data Type	Visibility Condition	Description
`Value`	`value`	`Bytes`	Always visible	Emits the configured constant in the selected data type (`Bytes`, `String`, `Int`, or `Bool`).

Error Cases

This node has no runtime failure cases (errorProfile: none) and always succeeds for any valid typed input.

Examples

Supplying a 128-bit AES Test Vector Key

Feed the NIST FIPS 197 Appendix B 16-byte key into an AES Encrypt node.

Set Type to Bytes (Hex).
Enter 2b7e151628aed2a6abf7158809cf4f3c in Value (Bytes).
Connect the Value output port to the Key input port of an AES Encrypt node.
