I'd like to do a data transfer without encryption but with a guarantee that my data comes from a legit source. I'm thinking something that uses a public key scheme to sign the data.
Does anyone know of something like that?
Thanks!

isupper
ISUPPER(3) BSD Library Functions Manual ISUPPER(3)NAME
isupper -- upper-case character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isupper(int c);
DESCRIPTION
The isupper() function tests for any upper-case letter. The value of the argument must be representable as an unsigned char or the value of
EOF.
In the ASCII character set, this includes the following characters (with their numeric values shown in octal):
101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E''
106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J''
113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O''
120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T''
125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y''
132 ``Z''
RETURN VALUES
The isupper() function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswupper() function should be used instead.
SEE ALSO ctype(3), iswupper(3), toupper(3), ascii(7)STANDARDS
The isupper() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
