The CrypterObject has a SHA function for creating a hash. Unfortunately the output is a blob.

How do I convert that to a string?

Blob lblb_data
Blob lblb_sha1
String ls_data

lblb_data = Blob("Test SHA1", EncodingANSI!)

CrypterObject lnv_CrypterObject
lnv_CrypterObject = Create CrypterObject

// Encrypt with SHA
lblb_sha1= lnv_CrypterObject.SHA(SHA1!, lblb_data)

Coderobject lnv_code
Lnv_code = create coderobject
//Encode the SHA blob data to be hex data and output as a string
Ls_data = lnv_code.hexencode(lblb_sha1)

lblb_hash = lcr_crypt.sha( SHA3_256! , lblb_valuetohash)
ls_hashstring = lcdr_coder.base64encode( lblb_hash )

Hi Roland;

  Due to the binary nature of the encryption, have you thought about outputting this data stream as a Base64 string?

Regards ... Chris
