Constructors

Constructor

new ShaBase(blockSize: number, finalSize: number): ShaBase;

Defined in: src/sha-base.ts:45

Creates a new instance of the hash base class.

Parameters

Parameter	Type	Description
blockSize	number	The size of the internal block buffer in bytes.
finalSize	number	The size of the final hash output in bytes.

Returns

ShaBase

Overrides

HashBase.constructor

Methods

digest()

Call Signature

digest(): Uint8Array;

Defined in: src/sha-base.ts:77

Finalizes the hash computation and returns the resulting hash digest. This method performs any necessary padding and processes the final block of data according to the hash algorithm's specification.

Returns

Uint8Array

The hash digest

Overrides

HashBase.digest

Call Signature

digest(encoding: BinaryEncoding): string;

Defined in: src/sha-base.ts:78

Finalizes the hash computation and returns the resulting hash digest. This method performs any necessary padding and processes the final block of data according to the hash algorithm's specification.

Parameters

Parameter	Type	Description
encoding	BinaryEncoding	Optional. The encoding to use for the output digest (e.g., 'hex', 'base64').

Returns

string

An encoded string, depending on the encoding parameter.

Overrides

HashBase.digest

---

update()

Call Signature

update(data: BinaryObject | ArrayLike<number>): this;

Defined in: src/sha-base.ts:119

Updates the hash with the given binary data.

Parameters

Parameter	Type	Description
data	BinaryObject | ArrayLike<number>	The data to update the hash with, as a BinaryObject.

Returns

this

The hash instance for method chaining.

Overrides

HashBase.update

Call Signature

update(data: string, encoding?: TextEncoding): this;

Defined in: src/sha-base.ts:120

Updates the hash with the given string data.

Parameters

Parameter	Type	Description
data	string	The string data to update the hash with.
encoding?	TextEncoding	Optional text encoding of the input string (e.g., 'utf8').

Returns

this

The hash instance for method chaining.

Overrides

HashBase.update
