FUNCTIONS

57   ripemd160
58       Logically joins all arguments into a single string, and returns its
59       RIPEMD160 digest encoded as a binary string.
60
61        $ripemd160_raw = ripemd160('data string');
62        #or
63        $ripemd160_raw = ripemd160('any data', 'more data', 'even more data');
64
65   ripemd160_hex
66       Logically joins all arguments into a single string, and returns its
67       RIPEMD160 digest encoded as a hexadecimal string.
68
69        $ripemd160_hex = ripemd160_hex('data string');
70        #or
71        $ripemd160_hex = ripemd160_hex('any data', 'more data', 'even more data');
72
73   ripemd160_b64
74       Logically joins all arguments into a single string, and returns its
75       RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.
76
77        $ripemd160_b64 = ripemd160_b64('data string');
78        #or
79        $ripemd160_b64 = ripemd160_b64('any data', 'more data', 'even more data');
80
81   ripemd160_b64u
82       Logically joins all arguments into a single string, and returns its
83       RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648
84       section 5).
85
86        $ripemd160_b64url = ripemd160_b64u('data string');
87        #or
88        $ripemd160_b64url = ripemd160_b64u('any data', 'more data', 'even more data');
89
90   ripemd160_file
91       Reads file (defined by filename or filehandle) content, and returns its
92       RIPEMD160 digest encoded as a binary string.
93
94        $ripemd160_raw = ripemd160_file('filename.dat');
95        #or
96        $ripemd160_raw = ripemd160_file(*FILEHANDLE);
97
98   ripemd160_file_hex
99       Reads file (defined by filename or filehandle) content, and returns its
100       RIPEMD160 digest encoded as a hexadecimal string.
101
102        $ripemd160_hex = ripemd160_file_hex('filename.dat');
103        #or
104        $ripemd160_hex = ripemd160_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   ripemd160_file_b64
110       Reads file (defined by filename or filehandle) content, and returns its
111       RIPEMD160 digest encoded as a Base64 string, with trailing '=' padding.
112
113        $ripemd160_b64 = ripemd160_file_b64('filename.dat');
114        #or
115        $ripemd160_b64 = ripemd160_file_b64(*FILEHANDLE);
116
117   ripemd160_file_b64u
118       Reads file (defined by filename or filehandle) content, and returns its
119       RIPEMD160 digest encoded as a Base64 URL Safe string (see RFC 4648
120       section 5).
121
122        $ripemd160_b64url = ripemd160_file_b64u('filename.dat');
123        #or
124        $ripemd160_b64url = ripemd160_file_b64u(*FILEHANDLE);
