This module implements binary data hashing algorithms. The exact inventory of available algorithms depends on a board. Among the algorithms which may be implemented:
SHA256 - The current generation, modern hashing algorithm (of SHA2 series). It is suitable for cryptographically-secure purposes. Included in the MicroPython core and any board is recommended to provide this, unless it has particular code size constraints.
SHA1 - A previous generation algorithm. Not recommended for new usages, but SHA1 is a part of number of Internet standards and existing applications, so boards targeting network connectivity and interoperability will try to provide this.
MD5 - A legacy algorithm, not considered cryptographically secure. Only selected boards, targeting interoperability with legacy applications, will offer this.
- class hashlib.sha256([data])¶
Create an SHA256 hasher object and optionally feed
- class hashlib.sha1([data])¶
Create an SHA1 hasher object and optionally feed
- class hashlib.md5([data])¶
Create an MD5 hasher object and optionally feed
Feed more binary data into hash.
Return hash for all data passed through hash, as a bytes object. After this method is called, more data cannot be fed into the hash any longer.
This method is NOT implemented. Use
binascii.hexlify(hash.digest())to achieve a similar effect.
