How do I convert string or a value to a byte array?
I need it for SOAP authentication. My requirement is to –
On the client side, this is how to create a digest:
1. Client Side Digest Array = byte array nonce + byte array UTC date-time of UTF-8 string + byte array UTF-8 plain text password (concatenate these three).
2. Client Side SHA-1 Digest = Hash with SHA-1 algorithm the Client Side Digest Array.
3. Client Side WS-Security Digest = 64-bit encode the Client Side SHA-1 Digest

Password_Digest = Base64 ( SHA-1 ( nonce + timestamp + password ) )

This is the code I am using to generate nonce, timestamp and digest_password. User password is a string. Some ting is wrong in the whole process and my digest is not successfully generated. I guess I have these data types right, byte array and UTF8 is confusing me.
I added utf8 conversion but no difference. 

def nonce
   chars = ("a".."z").to_a + ("1".."9").to_a + ("A".."Z").to_a
   @nonce = Array.new(20, '').collect{chars[rand(chars.size)]}.join
end

def timestamp
    t = Time.now.utc.strftime("%Y-%m-%dT%H:%M:%S.%LZ")
    @timestamp = t.to_s
end

def digest_password

ic = Iconv.new('UTF-8//IGNORE', 'US-ASCII')
$time =  ic.iconv( timestamp + ' ')[0..-2]
$pass =  ic.iconv( password + ' ')[0..-2]
temp = (nonce.bytes.to_a + $time.bytes.to_a + $pass.bytes.to_a)
@digest_password = Base64.strict_encode64(Digest::SHA1.hexdigest(temp.to_s))

###  temp =  Digest::SHA1.hexdigest(nonce + timestamp + password) ##old    
###@digest_password = Base64.encode64(temp) ##old

end

    Finally was able to solve this issue. 

    Password_Digest = Base64 ( SHA-1 ( nonce + create + password) )

    nonce = nonce as string. Before Base64 endoce, E.g “1234”

    create = time as string. No encoding

    password = password as string. No encoding.

    Base64Nonce = Base64.encode64(nonce).strip #Base64 encode of “1234”

    chars = ("a".."z").to_a + ("1".."9").to_a + ("A".."Z").to_a
nonce = Array.new(20, '').collect{chars[rand(chars.size)]}.join

t = Time.now.utc.strftime("%Y-%m-%dT%H:%M:%S.%LZ")

$time = t
$pass = p
Base64Nonce = Base64.encode64(nonce).strip 

$digest_pass = Base64.encode64(Digest::SHA1.digest(nonce + $time + $pass)).strip



          "wsse:Username" => username,
          "wsse:Password" => $digest_pass,
          "wsse:Nonce" => Base64Nonce,
          "wsu:Created" => $time,
