Properties

Readonly_DEV_XFORM_MODE

_DEV_XFORM_MODE: number

A constant representing decryption mode.

Readonly_ENC_XFORM_MODE

_ENC_XFORM_MODE: number

A constant representing encryption mode.

blockSize

blockSize: number

The number of 32-bit words this cipher operates on. Default: 1 (32 bits)

ivSize

ivSize: number

This cipher's IV size. Default: 4 (128 bits)

keySize

keySize: number

This cipher's key size. Default: 4 (128 bits)

Methods

finalize

  • finalize(dataUpdate?): cryptojs.lib.WordArray

  • Finalizes the encryption or decryption process. Note that the finalize operation is effectively a destructive, read-once operation.

    Parameters

    Returns cryptojs.lib.WordArray

    The data after final processing.

    Example

    var encrypted = cipher.finalize();
        var encrypted = cipher.finalize('data');
        var encrypted = cipher.finalize(wordArray);

process

  • process(dataUpdate): cryptojs.lib.WordArray

  • Adds data to be encrypted or decrypted.

    Parameters

    Returns cryptojs.lib.WordArray

    The data after processing.

    Example

    var encrypted = cipher.process('data');
        var encrypted = cipher.process(wordArray);

reset

  • reset(): void

  • Resets this cipher to its initial state.

    Returns void

    Example

    cipher.reset();
