blake3¶

Joins all arguments into a single string and returns its BLAKE3 digest encoded as a binary string.

Data arguments for the functional helpers are converted to byte strings using Perl's usual scalar stringification. Defined scalars, including numbers and string-overloaded objects, are accepted. "undef" is treated as an empty string and may emit Perl's usual "uninitialized value" warning. The same rules apply to "blake3_hex", "blake3_b64", and "blake3_b64u".

 my $blake3_raw = blake3('data string');
 #or
 my $blake3_raw = blake3('any data', 'more data', 'even more data');

blake3_hex¶

Joins all arguments into a single string and returns its BLAKE3 digest encoded as a hexadecimal string.

 my $blake3_hex = blake3_hex('data string');
 #or
 my $blake3_hex = blake3_hex('any data', 'more data', 'even more data');

blake3_b64¶

Joins all arguments into a single string and returns its BLAKE3 digest encoded as a Base64 string, with trailing '=' padding.

 my $blake3_b64 = blake3_b64('data string');
 #or
 my $blake3_b64 = blake3_b64('any data', 'more data', 'even more data');

blake3_b64u¶

Joins all arguments into a single string and returns its BLAKE3 digest encoded as a Base64 URL-safe string (see RFC 4648 section 5).

 my $blake3_b64url = blake3_b64u('data string');
 #or
 my $blake3_b64url = blake3_b64u('any data', 'more data', 'even more data');

blake3_file¶

Reads a file given by a filename or filehandle and returns its BLAKE3 digest encoded as a binary string.

 my $blake3_raw = blake3_file('filename.dat');
 #or
 my $filehandle = ...; # existing binary-mode filehandle
 my $blake3_raw = blake3_file($filehandle);

blake3_file_hex¶

Reads a file given by a filename or filehandle and returns its BLAKE3 digest encoded as a hexadecimal string.

 my $blake3_hex = blake3_file_hex('filename.dat');
 #or
 my $filehandle = ...; # existing binary-mode filehandle
 my $blake3_hex = blake3_file_hex($filehandle);

Note: The filehandle must be in binary mode before you pass it to addfile().

blake3_file_b64¶

Reads a file given by a filename or filehandle and returns its BLAKE3 digest encoded as a Base64 string, with trailing '=' padding.

 my $blake3_b64 = blake3_file_b64('filename.dat');
 #or
 my $filehandle = ...; # existing binary-mode filehandle
 my $blake3_b64 = blake3_file_b64($filehandle);

blake3_file_b64u¶

Reads a file given by a filename or filehandle and returns its BLAKE3 digest encoded as a Base64 URL-safe string (see RFC 4648 section 5).

 my $blake3_b64url = blake3_file_b64u('filename.dat');
 #or
 my $filehandle = ...; # existing binary-mode filehandle
 my $blake3_b64url = blake3_file_b64u($filehandle);

new¶

 my $d = Crypt::Digest::BLAKE3->new();

clone¶

 $d->clone();

reset¶

 $d->reset();

add¶

Appends data to the message. Returns the object itself (for chaining).

Each argument is converted to bytes using Perl's usual scalar stringification. Defined scalars, including numbers and string-overloaded objects, are accepted. "undef" is treated as an empty string and may emit Perl's usual "uninitialized value" warning.

 $d->add('any data');
 #or
 $d->add('any data', 'more data', 'even more data');

addfile¶

Reads the file content and appends it to the message. Returns the object itself (for chaining).

 $d->addfile('filename.dat');
 #or
 my $filehandle = ...; # existing binary-mode filehandle
 $d->addfile($filehandle);

hashsize¶

 $d->hashsize;
 #or
 Crypt::Digest::BLAKE3->hashsize();
 #or
 Crypt::Digest::BLAKE3::hashsize();

digest¶

Returns the binary digest (raw bytes). The first call finalizes the digest object. Any later add(), addfile(), digest(), hexdigest(), b64digest(), or b64udigest() call will fail until you call reset().

 my $result_raw = $d->digest();

hexdigest¶

Returns the digest encoded as a lowercase hexadecimal string. Like digest(), the first call finalizes the digest object.

 my $result_hex = $d->hexdigest();

b64digest¶

Returns the digest encoded as a Base64 string with trailing "=" padding. Like digest(), the first call finalizes the digest object.

 my $result_b64 = $d->b64digest();

b64udigest¶

Returns the digest encoded as a Base64 URL-safe string (no trailing "="). Like digest(), the first call finalizes the digest object.

 my $result_b64url = $d->b64udigest();
