crypto
The crypto object is
global object that allows using cryptographic functionality (since @ZO)
crypto.getRandomValues(typedArray)
Gets cryptographically strong random values_
Returns the
same array passed as typedArray but with its
contents replaced with the newly generated random numbers.
Possible values:
typedArray
can be Int8Array, Intl6Array, Uintl6Array, Int32Array, Or Uint32Array
crypto.subtle.encrypt(algorithm_
key: data)
Encrypts
data using the
provided algorithu and
Returns
Promise
that fulfills with an ArrayBuffer
containing the ciphertext: Possible values:
algorithm
an
object that specifies the algorithm to be used and any extra parameters if required:
for RSA - OAEP
pass the object with the following keys:
name IS a
string, should be set to RSA
OAEP

data)
for AES- CTR, pass the object with the following keys:
name IS a
string, should be set to AES-CTR
counter is
an ArrayBuffer,
TypedArray
DataView
the initial value of the counter block;
must be 16 bytes long (the AES block size). The rightmost length bits of this block are used
for the counter; and the rest is used for the nonce
For example, if length is set to 64, then the
first half of counter is the nonce and the second half is used for the counter
Length is the number of bits in the counter block that are used for the actual counter The
counter must be big enough that it doesn't wrap
for AES-CBC
pass the object with the following keys:
name is a
string, should be set to AES
CBC
