Methods

(static) cachedPbkdf2(password, objopt) → {Object}

Cached PBKDF2 key derivation.
Parameters:
Name Type Attributes Description
password String The password.
obj Object <optional>
 The derivation params (iteration count and optional salt).
Source:
Returns:
The derived data in key, the salt in salt.
Type
Object

(static) hkdf(ikm, keyBitLength, salt, info, Hashopt) → {bitArray}

HKDF with the specified hash function.
Parameters:
Name Type Attributes Default Description
ikm bitArray The input keying material.
keyBitLength Number The output key length, in bits.
salt String | bitArray The salt for HKDF.
info String | bitArray The info for HKDF.
Hash Object <optional>
 sjcl.hash.sha256 The hash function to use.
Source:
Returns:
derived key.
Type
bitArray

(static) pbkdf2(password, salt, countopt, lengthopt, Prffopt) → {bitArray}

Password-Based Key-Derivation Function, version 2.0. Generate keys from passwords using PBKDF2-HMAC-SHA256. This is the method specified by RSA's PKCS #5 standard.
Parameters:
Name Type Attributes Default Description
password bitArray | String The password.
salt bitArray | String The salt. Should have lots of entropy.
count Number <optional>
 1000 The number of iterations. Higher numbers make the function slower but more secure.
length Number <optional>
 The length of the derived key. Defaults to the output size of the hash function.
Prff Object <optional>
 sjcl.misc.hmac The pseudorandom function family.
Source:
Returns:
the derived key.
Type
bitArray

(static) scrypt(password, salt, Nopt, ropt, popt, lengthopt, Prffopt) → {bitArray}

scrypt Password-Based Key-Derivation Function.
Parameters:
Name Type Attributes Default Description
password bitArray | String The password.
salt bitArray | String The salt. Should have lots of entropy.
N Number <optional>
 16384 CPU/Memory cost parameter.
r Number <optional>
 8 Block size parameter.
p Number <optional>
 1 Parallelization parameter.
length Number <optional>
 The length of the derived key. Defaults to the output size of the hash function.
Prff Object <optional>
 sjcl.misc.hmac The pseudorandom function family.
Source:
Returns:
The derived key.
Type
bitArray
