Hello,

I followed the example of the help to encrypt in MD5; however, the result is not as expected.

Let's see, this is the example:

Blob lblb_data
Blob lblb_md5
String ls_resultMD5

lblb_data = Blob("Test MD5", EncodingANSI!)

CrypterObject lnv_CrypterObject
lnv_CrypterObject = Create CrypterObject

// Encrypt with MD5
lblb_md5 = lnv_CrypterObject.MD5(lblb_data)

ls_resultMD5	= String(lblb_md5, EncodingANSI!)

sle_result.text	= ls_resultMD5

 

According to https://md5online.es/cifrar-md5 and other means of encryption, the result for "Test MD5" is 17b5cb0adb7fc8a14dbe55c312d84604 however, the result for "Test MD5" obtained from PowerBuilder is µËÛÈ¡M¾UÃØF

 

I use PB 2017 R3 1880

 

Any ideas about it?

Thank you

Hello Jorge,

you need a CoderObject in between.

Best,

.m

 

Blob lblb_data
Blob lblb_key
Blob lblb_hash
lblb_data = Blob("Test MD5", EncodingANSI!)
lblb_key = Blob("Hashing Test", EncodingANSI!)

lnv_CrypterObject = Create CrypterObject
lnv_CoderObject = Create CoderObject

lblb_hash = lnv_CrypterObject.MD5(lblb_data)
ls_hash = lnv_CoderObject.HexEncode(lblb_hash)
lblb_hash = Blob(ls_hash, EncodingANSI!)

sle_result.Text = String(lblb_hash, EncodingANSI!)

The website shows the result in HEX. You can use the CoderObject to get the Hex String from a blob:

CoderObject lnv_CoderObject
lnv_CoderObject = Create CoderObject

ls_resultMD5 = lnv_CoderObject.HexEncode( lblb_md5 )

Hi Jorge; 

   To get this in hex, write the value in the Blob variable to a file & then view the file in a hex editor. You should then see the same values.

That isn't a very good solution. There should be an option to return it as a hex string.

FWIW ... I would personally prefer that the PB Debugger be enhanced to let you view Blob datum in Hex format. ;-)

My BCrypt example gives the correct result:

Not sure why the built-in function is like that.
