OpenSSL encryption/decryption remove multiple white spaces to only one - encryption

Question

I have an issue trying to use openssl command to encrypt and decrypt varchar2 variables with text data and multiples white spaces between.
I can encrypt/decrypt, but the output remove multiple white spaces inside the decrypted text. I've tried several ways process the text with urlencode/urldecode and base64encode/base64decode. But the decrypted text is always the same. Maybe white spaces doesn't matter for openssl or what I am doing wrong?
--Code:
--Encrypt
DECLARE
l_output DBMS_OUTPUT.chararr;
l_lines INTEGER := 1000;
key_value VARCHAR2(200) := 'thisisthekeytoencryptdecrypt';
command VARCHAR2(1000);
text_encrypt VARCHAR2(1000);
text_value VARCHA2(50):= '11 22 444';
BEGIN
command:='echo '||texto_value||'|/usr/bin/openssl enc -aes-256-cbc -e -base64 -A -pass pass:'||key_value;
host_command(comand);
DBMS_OUTPUT.get_lines(l_output, l_lines);
FOR i IN 1 .. l_lines LOOP
text_encrypt:=text_encrypt||substr(l_output(i),14);
END LOOP;
DBMS_OUTPUT.put_line('text_Encrypted:'|| text_encrypt);
END;

The problem is that you're passing this through the shell:
command:='echo '||texto_value||'|/usr/bin/openssl enc -aes-256-cbc -e -base64 -A -pass pass:'||key_value;
The shell is removing the spaces before sending to the echo command. You'll need to put quotes around the value, probably along these lines (note placement of "):
command:='echo "'||texto_value||'"|/usr/bin/openssl enc -aes-256-cbc -e -base64 -A -pass pass:'||key_value;
