hmac¶
Keyed-hashing for message authentication (HMAC).
Functions¶
hmac.new(key: Bytes, msg: Bytes | None = None, digestmod: str = "sha256") -> HmacObject¶
Create a new HMAC object from a byte key.
hmac.new(key: str, msg: str | None = None, digestmod: str = "sha256") -> HmacObject¶
Create a new HMAC object from a string key.
hmac.digest(key: Bytes, msg: Bytes, digestmod: str) -> Bytes¶
Compute an HMAC digest for a byte message.
hmac.digest(key: str, msg: str, digestmod: str) -> Bytes¶
Compute an HMAC digest for a string message.
hmac.compare_digest(a: str, b: str) -> bool¶
Compare two strings in constant time.
hmac.compare_digest(a: Bytes, b: Bytes) -> bool¶
Compare two byte sequences in constant time.
HmacObject¶
Represents an incremental HMAC computation.
Properties¶
| Name | Type | Description |
|---|---|---|
digest_size |
int |
Get the digest size in bytes. |
name |
str |
Get the canonical algorithm name for this HMAC. |
update(data: str)¶
Update the HMAC with string data.
update(data: Bytes)¶
Update the HMAC with byte data.
hexdigest() -> str¶
Return the current digest as lowercase hexadecimal text.
digest() -> list[int]¶
Return the current digest as a list of byte values.
copy() -> HmacObject¶
Return a copy of this HMAC object.
