9 ### Functional interface:
10 use Crypt::Digest::BLAKE2s_224 qw( blake2s_224 blake2s_224_hex blake2s_224_b64 blake2s_224_b64u

13 # calculate digest from string/buffer
14 $blake2s_224_raw = blake2s_224('data string');
15 $blake2s_224_hex = blake2s_224_hex('data string');
16 $blake2s_224_b64 = blake2s_224_b64('data string');

23 # calculate digest from filehandle
24 $blake2s_224_raw = blake2s_224_file(*FILEHANDLE);
25 $blake2s_224_hex = blake2s_224_file_hex(*FILEHANDLE);
26 $blake2s_224_b64 = blake2s_224_file_b64(*FILEHANDLE);
27 $blake2s_224_b64u = blake2s_224_file_b64u(*FILEHANDLE);
28
29 ### OO interface:
30 use Crypt::Digest::BLAKE2s_224;
31
32 $d = Crypt::Digest::BLAKE2s_224->new;
33 $d->add('any data');
34 $d->addfile('filename.dat');
35 $d->addfile(*FILEHANDLE);
36 $result_raw = $d->digest; # raw bytes
37 $result_hex = $d->hexdigest; # hexadecimal form
38 $result_b64 = $d->b64digest; # Base64 form
39 $result_b64u = $d->b64udigest; # Base64 URL Safe form

42 Provides an interface to the BLAKE2s_224 digest algorithm.
43
45 Nothing is exported by default.
46
47 You can export selected functions:
48
49 use Crypt::Digest::BLAKE2s_224 qw(blake2s_224 blake2s_224_hex blake2s_224_b64 blake2s_224_b64u
50 blake2s_224_file blake2s_224_file_hex blake2s_224_file_b64 blake2s_224_file_b64u);
51
52 Or all of them at once:
53
54 use Crypt::Digest::BLAKE2s_224 ':all';
55
57 blake2s_224
58 Logically joins all arguments into a single string, and returns its
59 BLAKE2s_224 digest encoded as a binary string.
60
61 $blake2s_224_raw = blake2s_224('data string');
62 #or
63 $blake2s_224_raw = blake2s_224('any data', 'more data', 'even more data');
64
65 blake2s_224_hex
66 Logically joins all arguments into a single string, and returns its
67 BLAKE2s_224 digest encoded as a hexadecimal string.
68
69 $blake2s_224_hex = blake2s_224_hex('data string');
70 #or
71 $blake2s_224_hex = blake2s_224_hex('any data', 'more data', 'even more data');
72
73 blake2s_224_b64
74 Logically joins all arguments into a single string, and returns its
75 BLAKE2s_224 digest encoded as a Base64 string, with trailing '='
76 padding.
77
78 $blake2s_224_b64 = blake2s_224_b64('data string');
79 #or
80 $blake2s_224_b64 = blake2s_224_b64('any data', 'more data', 'even more data');
81
82 blake2s_224_b64u
83 Logically joins all arguments into a single string, and returns its
84 BLAKE2s_224 digest encoded as a Base64 URL Safe string (see RFC 4648
85 section 5).
86
87 $blake2s_224_b64url = blake2s_224_b64u('data string');
88 #or
89 $blake2s_224_b64url = blake2s_224_b64u('any data', 'more data', 'even more data');
90
91 blake2s_224_file
92 Reads file (defined by filename or filehandle) content, and returns its
93 BLAKE2s_224 digest encoded as a binary string.
94
95 $blake2s_224_raw = blake2s_224_file('filename.dat');
96 #or
97 $blake2s_224_raw = blake2s_224_file(*FILEHANDLE);
98
99 blake2s_224_file_hex
100 Reads file (defined by filename or filehandle) content, and returns its
101 BLAKE2s_224 digest encoded as a hexadecimal string.
102
103 $blake2s_224_hex = blake2s_224_file_hex('filename.dat');
104 #or
105 $blake2s_224_hex = blake2s_224_file_hex(*FILEHANDLE);
106
107 BEWARE: You have to make sure that the filehandle is in binary mode
108 before you pass it as argument to the addfile() method.
109
110 blake2s_224_file_b64
111 Reads file (defined by filename or filehandle) content, and returns its
112 BLAKE2s_224 digest encoded as a Base64 string, with trailing '='
113 padding.
114
115 $blake2s_224_b64 = blake2s_224_file_b64('filename.dat');
116 #or
117 $blake2s_224_b64 = blake2s_224_file_b64(*FILEHANDLE);
118
119 blake2s_224_file_b64u
120 Reads file (defined by filename or filehandle) content, and returns its
121 BLAKE2s_224 digest encoded as a Base64 URL Safe string (see RFC 4648
122 section 5).
123
124 $blake2s_224_b64url = blake2s_224_file_b64u('filename.dat');
125 #or
126 $blake2s_224_b64url = blake2s_224_file_b64u(*FILEHANDLE);
