Module crypto

Classes

• class InvalidAlgorithm
  Algorithm is not supported by hashlib.

Functions

• ▶ def constant_time_compare(val1, val2)

  Return True if the two strings are equal, False otherwise.

  Reexports

  • Imported in django.contrib.auth.
  • Imported in django.contrib.auth.hashers.
  • Imported in django.contrib.auth.tokens.
  • Imported in django.contrib.messages.storage.cookie.
  • Imported in django.contrib.sessions.backends.base.
  • Imported in django.core.signing.
  • Imported in django.middleware.csrf.
• ▶ def get_random_string(length=NOT_PROVIDED, ...)

  Return a securely generated random string.

  def get_random_string(

  length=NOT_PROVIDED,

  allowed_chars='abcdefghijklmnopqrstuvwxyz' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789',

  )

  The bit length of the returned value can be calculated with the formula:
      log_2(len(allowed_chars)^length)
  
  For example, with default `allowed_chars` (26+26+10), this gives:
    * length: 12, bit length =~ 71 bits
    * length: 22, bit length =~ 131 bits

• ▶ def pbkdf2(password, salt, iterations, dklen=0, digest=None)

  Return the hash of password using pbkdf2.

  Reexports

  • Imported in django.contrib.auth.hashers.
• ▶ def salted_hmac(key_salt, value, secret=None, *, algorithm='sha1')

  Return the HMAC of 'value', using a key generated from key_salt and a secret (which defaults to settings.SECRET_KEY). Default algorithm is SHA1, but any algorithm name supported by hashlib can be passed.

  source link

  A different key_salt should be passed in for every application of HMAC.
