[−][src]Struct sha1collisiondetection::Builder
Configures the collision-detecting SHA-1 algorithm.
Implementations
impl Builder
[src]
pub fn safe_hash(self, v: bool) -> Self
[src]
Configures collision mitigation.
Collision attacks are thwarted by hashing a detected near-collision block 3 times. Think of it as extending SHA-1 from 80-steps to 240-steps for such blocks: The best collision attacks against SHA-1 have complexity about 2^60, thus for 240-steps an immediate lower-bound for the best cryptoanalytic attacks would be 2^180. An attacker would be better off using a generic birthday search of complexity 2^80.
Enabling safe SHA-1 hashing will result in the correct SHA-1 hash for messages where no collision attack was detected, but it will result in a different SHA-1 hash for messages where a collision attack was detected. This will automatically invalidate SHA-1 based digital signature forgeries.
Enabled by default.
pub fn use_ubc(self, v: bool) -> Self
[src]
Configures use of Unavoidable Bitconditions.
This provides a significant speed up.
Enabled by default.
pub fn detect_collisions(self, v: bool) -> Self
[src]
Configures collision detection.
Enabled by default.
pub fn build(self) -> Sha1CDⓘ
[src]
Finalizes the configuration.
