Android Question sha1(md5(string))

[Douglas Farias]

hi all, i need send to my php server this information via post
sha1(md5(stringcomasenha)) it is a password of the users
how i made this on b4a?

md5 i see on the forum but md5 + sha1 ????

sha1 is also common, especially in data connection encryptions.

worst case you send as MD5 and do the extra SHA1 on the php side

can u show me a sample to send?
i need to send sha1(md5(lala)) for example.

I don't know if B4A supports both of them, you'll need to search for it.

Done i made it. if help someone its here xD

    Private pi As String
    pi = "laleqwe"
    Dim md As MessageDigest
    Dim ByteCon As ByteConverter
    Dim passwordhash() As Byte
    Dim passwordhash2() As Byte
    passwordhash = md.GetMessageDigest(pi.GetBytes("UTF8"),"MD5")
    Dim md5string As String
    md5string = ByteCon.HexFromBytes(passwordhash)
    Log(md5string)
    passwordhash2 = md.GetMessageDigest(md5string.GetBytes("UTF8"),"SHA-1")
    Dim SHA1string As String
    SHA1string = ByteCon.HexFromBytes(passwordhash2)
    Log(SHA1string)

you see that the search is powerfull enough to find what you need (in most case)

opss

    Private pi As String
    pi = "laleqwe"
    Dim md As MessageDigest
    Dim ByteCon As ByteConverter
    Dim passwordhash() As Byte
    Dim passwordhash2() As Byte
    passwordhash = md.GetMessageDigest(pi.GetBytes("UTF8"),"MD5")
    Dim md5string As String
    md5string = ByteCon.HexFromBytes(passwordhash)
    md5string = md5string.ToLowerCase
    Log(md5string)
    passwordhash2 = md.GetMessageDigest(md5string.GetBytes("UTF8"),"SHA-1")
    Dim SHA1string As String
    SHA1string = ByteCon.HexFromBytes(passwordhash2)
    SHA1string = SHA1string.ToLowerCase
    Log(SHA1string)

here is the code correct need convert to lower case *-*
