DESCRIPTION
The "Digest::BLAKE2" module provides an interface to the BLAKE2 message
digest algorithm.
The cryptographic hash function BLAKE2 is an improved version of the
SHA-3 finalist BLAKE. Like BLAKE or SHA-3, BLAKE2 offers the highest
security, yet is fast as MD5 on 64-bit platforms and requires at least
33% less RAM than SHA-2 or SHA-3 on low-end systems.
BLAKE2 comes in two flavors. BLAKE2b is optimized for 64-bit
platforms—including NEON-enabled ARMs—and produces digests of any
size between 1 and 64 bytes. BLAKE2s is optimized for 8- to 32-bit
platforms and produces digests of any size between 1 and 32 bytes.
This interface follows the conventions set forth by the "Digest" module.
FUNCTIONS
None of these functions are exported by default.
blake2b($data, ...)
blake2s($data, ...)
Logically joins the arguments into a single string, and returns its
BLAKE2 digest encoded as a binary string.
blake2b_hex($data, ...)
blake2s_hex($data, ...)
Logically joins the arguments into a single string, and returns its
BLAKE2 digest encoded as a hexadecimal string.
blake2b_base64($data, ...)
blake2s_base64($data, ...)
Logically joins the arguments into a single string, and returns its
BLAKE2 digest encoded as a Base64 string, without any trailing padding.
blake2b_base64url($data, ...)
blake2s_base64url($data, ...)
Logically joins the arguments into a single string, and returns its
BLAKE2 digest encoded as a urlsafe Base64 string, without any trailing
padding.
blake2b_ascii85($data, ...)
blake2s_ascii85($data, ...)
Logically joins the arguments into a single string, and returns its
BLAKE2 digest encoded as a Ascii85 string, without any trailing padding.
