Methods

export

export(
exporterContext: ArrayBufferLike | ArrayBufferView,
len: number,
): Promise<ArrayBuffer>
Exports a secret using a variable-length pseudorandom function.

If the error occurred, throws ExportError.
Parameters
- exporterContext: ArrayBufferLike | ArrayBufferView
  An exporter context string as bytes. The maximum length is 128 bytes.
- len: number
  A desired length in bytes of the output secret.
Returns Promise<ArrayBuffer>
A secret string as bytes.

Throws
ExportError

open

open(
data: ArrayBufferLike | ArrayBufferView,
aad?: ArrayBufferLike | ArrayBufferView,
): Promise<ArrayBuffer>
Decrypts data.

If the error occurred, throws OpenError.
Parameters
- data: ArrayBufferLike | ArrayBufferView
  An encrypted text as bytes to be decrypted.
- Optionalaad: ArrayBufferLike | ArrayBufferView
  Additional authenticated data as bytes fed by an application.
Returns Promise<ArrayBuffer>
A decrypted plain text as bytes.

Throws
OpenError

seal

seal(
data: ArrayBufferLike | ArrayBufferView,
aad?: ArrayBufferLike | ArrayBufferView,
): Promise<ArrayBuffer>
Encrypts data.

If the error occurred, throws SealError | MessageLimitReachedError.
Parameters
- data: ArrayBufferLike | ArrayBufferView
  A plain text as bytes to be encrypted.
- Optionalaad: ArrayBufferLike | ArrayBufferView
  Additional authenticated data as bytes fed by an application.
Returns Promise<ArrayBuffer>
A cipher text as bytes.
