9 ### Functional interface:
10 use Crypt::Digest::SHA224 qw( sha224 sha224_hex sha224_b64 sha224_b64u
11 sha224_file sha224_file_hex sha224_file_b64 sha224_file_b64u );
12
13 # calculate digest from string/buffer
14 $sha224_raw = sha224('data string');
15 $sha224_hex = sha224_hex('data string');
16 $sha224_b64 = sha224_b64('data string');
17 $sha224_b64u = sha224_b64u('data string');
18 # calculate digest from file
19 $sha224_raw = sha224_file('filename.dat');
20 $sha224_hex = sha224_file_hex('filename.dat');
21 $sha224_b64 = sha224_file_b64('filename.dat');
22 $sha224_b64u = sha224_file_b64u('filename.dat');
23 # calculate digest from filehandle
24 $sha224_raw = sha224_file(*FILEHANDLE);
25 $sha224_hex = sha224_file_hex(*FILEHANDLE);
26 $sha224_b64 = sha224_file_b64(*FILEHANDLE);
27 $sha224_b64u = sha224_file_b64u(*FILEHANDLE);
28
29 ### OO interface:
30 use Crypt::Digest::SHA224;
31
32 $d = Crypt::Digest::SHA224->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
40
42 Provides an interface to the SHA224 digest algorithm.
43
45 Nothing is exported by default.
46
47 You can export selected functions:
48
49 use Crypt::Digest::SHA224 qw(sha224 sha224_hex sha224_b64 sha224_b64u
50 sha224_file sha224_file_hex sha224_file_b64 sha224_file_b64u);
51
52 Or all of them at once:
53
54 use Crypt::Digest::SHA224 ':all';
55
57 sha224
58 Logically joins all arguments into a single string, and returns its
59 SHA224 digest encoded as a binary string.
60
61 $sha224_raw = sha224('data string');
62 #or
63 $sha224_raw = sha224('any data', 'more data', 'even more data');
64
65 sha224_hex
66 Logically joins all arguments into a single string, and returns its
67 SHA224 digest encoded as a hexadecimal string.
68
69 $sha224_hex = sha224_hex('data string');
70 #or
71 $sha224_hex = sha224_hex('any data', 'more data', 'even more data');
72
73 sha224_b64
74 Logically joins all arguments into a single string, and returns its
75 SHA224 digest encoded as a Base64 string, with trailing '=' padding.
76
77 $sha224_b64 = sha224_b64('data string');
78 #or
79 $sha224_b64 = sha224_b64('any data', 'more data', 'even more data');
80
81 sha224_b64u
82 Logically joins all arguments into a single string, and returns its
83 SHA224 digest encoded as a Base64 URL Safe string (see RFC 4648 section
84 5).
85
86 $sha224_b64url = sha224_b64u('data string');
87 #or
88 $sha224_b64url = sha224_b64u('any data', 'more data', 'even more data');
89
90 sha224_file
91 Reads file (defined by filename or filehandle) content, and returns its
92 SHA224 digest encoded as a binary string.
93
94 $sha224_raw = sha224_file('filename.dat');
95 #or
96 $sha224_raw = sha224_file(*FILEHANDLE);
97
98 sha224_file_hex
99 Reads file (defined by filename or filehandle) content, and returns its
100 SHA224 digest encoded as a hexadecimal string.
101
102 $sha224_hex = sha224_file_hex('filename.dat');
103 #or
104 $sha224_hex = sha224_file_hex(*FILEHANDLE);
105
106 BEWARE: You have to make sure that the filehandle is in binary mode
107 before you pass it as argument to the addfile() method.
108
109 sha224_file_b64
110 Reads file (defined by filename or filehandle) content, and returns its
111 SHA224 digest encoded as a Base64 string, with trailing '=' padding.
112
113 $sha224_b64 = sha224_file_b64('filename.dat');
114 #or
115 $sha224_b64 = sha224_file_b64(*FILEHANDLE);
116
117 sha224_file_b64u
118 Reads file (defined by filename or filehandle) content, and returns its
119 SHA224 digest encoded as a Base64 URL Safe string (see RFC 4648 section
120 5).
121
122 $sha224_b64url = sha224_file_b64u('filename.dat');
123 #or
124 $sha224_b64url = sha224_file_b64u(*FILEHANDLE);
125
