MD2¶
MD2 is specified in RFC1319 and it produces the 128 bit digest of a message. For example:
>>> from Crypto.Hash import MD2
>>>
>>> h = MD2.new()
>>> h.update(b'Hello')
>>> print h.hexdigest()
MD2 stand for Message Digest version 2, and it was invented by Rivest in 1989.
Warning
This algorithm is not considered secure. Do not use it for new designs.
- class Crypto.Hash.MD2.MD2Hash(data=None)¶
An MD2 hash object. Do not instantiate directly. Use the
new()function.- Variables:
oid (string) – ASN.1 Object ID
block_size (integer) – the size in bytes of the internal message block, input to the compression function
digest_size (integer) – the size in bytes of the resulting hash
- copy()¶
Return a copy (“clone”) of the hash object.
The copy will have the same internal state as the original hash object. This can be used to efficiently compute the digests of strings that share a common initial substring.
- Returns:
A hash object of the same type
- digest()¶
Return the binary (non-printable) digest of the message that has been hashed so far.
- Returns:
The hash digest, computed over the data processed so far. Binary form.
- Return type:
byte string
- hexdigest()¶
Return the printable digest of the message that has been hashed so far.
- Returns:
The hash digest, computed over the data processed so far. Hexadecimal encoded.
- Return type:
string
- update(data)¶
Continue hashing of a message by consuming the next chunk of data.
- Parameters:
data (byte string/byte array/memoryview) – The next chunk of the message being hashed.
- Crypto.Hash.MD2.new(data=None)¶
Create a new hash object.
- Parameters:
data (bytes/bytearray/memoryview) – Optional. The very first chunk of the message to hash. It is equivalent to an early call to
MD2Hash.update().- Return:
A
MD2Hashhash object
