crypto
The crypto object is a global object that allows using cryptographic functionality (since 0ZO)
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, IntlbArray, UintlbArray, Int32Array
Or Uint32Array
crypto.subtle.encrypt(algorithu
key; data)
Encrypts data using the provided algorithy and key: Returns
Promise that fulfills with an ArrayBuffer
containing the ciphertext: Possible values:
algorithm
an
object that specifies the algorithm to be used and
extra parameters if required:
for RSA- OAEP
pass the object with the following keys:
name is a string, should be set to RSA-OAEP:
crypto.subtle .encrypt
{name:
RSA-OAEP"}
key ,
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_
Or 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 doesnt wrap
for AES- CBC
pass the object with the following keys:
name IS a
string, should be set to AES-CBC
iv or the initialization vector; is an ArrayBuffer
TypedArray,
Or DataView;
must be 16 bytes_
unpredictable_
and preferably cryptographically random:
However; it need not be secret, for
