(The header fields are Q/B decoded if necessary, # converted to the utf-8 encoding, concatenated, and hashed using MD5.) # The 16-byte MD5 hash is returned as an encoded string (such as base64, url, hex, etc.) # If the bFold argument is true, then the 16-byte MD5 hash is folded to 8 bytes with an XOR to produce a shorter key. set bFold 0 set key [CkEmail_computeGlobalKey $email "hex" $bFold] puts "key: $key" delete_CkEmail $email |
