Methods

`Static` blake2bHash

blake2bHash(x, length?): Uint8Array
It hashes the input using the blake2b algorithm.
Parameters
- x: Uint8Array
  
  The input to the hash function.
- Optional length: number = 32
  
  The length of the output hash in bytes.
Returns Uint8Array
The hash of the input.
- Defined in cryptography/utils/crypto-utils.ts:108

`Static` digestSHA512

digestSHA512(data, key): {
chainCode: Uint8Array;
key: Uint8Array;
}
It uses the HMAC function to generate a key and chain code.
Parameters
- data: Hex
  
  The data to be hashed.
- key: Hex
  
  The private key.
Returns {
chainCode: Uint8Array;
key: Uint8Array;
}
an object with two properties: key and chainCode.
- chainCode: Uint8Array
- key: Uint8Array
- Defined in cryptography/utils/crypto-utils.ts:27

`Static` `Private` ensurePbkdf2Input

ensurePbkdf2Input(salt, iterations, keySize): void
Parameters
- salt: Uint8Array
- iterations: number
- keySize: number
Returns void
- Defined in cryptography/utils/crypto-utils.ts:139

`Static` getCrypto

getCrypto(): Crypto
Returns the crypto instance which is resolved based on the envrionment

Returns Crypto
- Defined in cryptography/utils/crypto-utils.ts:131

`Static` hash160

hash160(data): Uint8Array
Given a byte array, return the hash160 of the sha256 of the byte array
Parameters
- data: Hex
  
  The data to be hashed.
Returns Uint8Array
The hash160 of the input data.
- Defined in cryptography/utils/crypto-utils.ts:69

`Static` hash256

hash256(data): Uint8Array
It hashes the data using the SHA-256 algorithm.
Parameters
- data: Hex
  
  The data to be hashed.
Returns Uint8Array
The hash256 function returns a hash256 value.
- Defined in cryptography/utils/crypto-utils.ts:53

`Static` pbkdf2Sync

pbkdf2Sync(password, salt, iterations, keySize): Uint8Array
It hashes the password using the PBKDF2 algorithm.
Parameters
- password: Uint8Array
  
  The password to use for the key derivation.
- salt: Uint8Array
  
  A salt to use for the key derivation function (salt's length must be from 16).
- iterations: number
  
  The number of iterations to perform (must be from 120k).
- keySize: number
  
  The size of the derived key in bytes (must be from 16).
Returns Uint8Array
The PBKDF2 function returns a Uint8Array.
- Defined in cryptography/utils/crypto-utils.ts:88

`Static` randomBytes

randomBytes(len): Uint8Array
Generate a random array of bytes of the given length
Parameters
- len: number
  
  the length of the random bytes to generate.
Returns Uint8Array
A random Uint8Array of length len.
- Defined in cryptography/utils/crypto-utils.ts:98

`Static` scrypt

scrypt(input, salt): Uint8Array
Create a strong private key from any input, where the key is longer and more secure.
Parameters
- input: string
- salt: Uint8Array
Returns Uint8Array
- Defined in cryptography/utils/crypto-utils.ts:120
