I writed this code: server.pl:

sub server {
# my $plaintext = $cipher->decrypt($buf);
# my $in = "SERVER: Text: ".$plaintext;
# my $ciphertext = $cipher->encrypt($in);
# print($new_sock $ciphertext);
my $plaintext = decrypt($buf);
my $in = "SERVER: Text: ".$plaintext;
my $ciphertext = crypt_($in);
}

sub crypt_ {
$cipher->start('encrypting');
print $sock $cipher->crypt($_) while <STDIN>;
print $sock $cipher->finish();
}
sub decrypt {
$cipher->start('decrypting');
local $/ = \4096;
process_bytes($cipher->crypt($_)) while <$sock>;
process_bytes($cipher->finish());
}

client.pl:

if ($kid) {
    # parent reads from STDIN, prints to socket
    while (defined($in = <STDIN>)) {
#     my $ciphertext = $cipher->encrypt($in);
#     print $ciphertext;
#    print $sock $ciphertext;
   my $ciphertext = crypt_($in);
    }
    # kill the child process
    kill(TERM => $kid);
} else {
    # child reads from socket, prints to STDOUT
    while (defined($buf = <$sock>)) {
#       my $plaintext = $cipher->decrypt($buf);
#    print $plaintext;
   my $plaintext = decrypt($buf);
   print $plaintext;
    }
    close $sock;
}
sub crypt_ {
$cipher->start('encrypting');
print $sock $cipher->crypt($_) while <STDIN>;
print $sock $cipher->finish();
}
sub decrypt {
$cipher->start('decrypting');
local $/ = \4096;
process_bytes($cipher->crypt($_)) while <$sock>;
process_bytes($cipher->finish());
}

In output from server.pl i have error:

wmp@innocence:~/ISS/iss/daemon$ ./server.pl
Undefined subroutine &main::process_bytes called at ./server.pl line 6
+6.
wmp@innocence:~/ISS/iss/daemon$

In client.pl again I must clicks enter. How to i can use IO::Socket::SSL ?
