Convert between String/Hex/Byte - wrong format?
Convert between String/Hex/Byte - wrong format?
I am trying to convert a bitcoin address and have the following code from here (Calculate Segwit address from public address, 2nd answer):
Step1: $ printf 1L88S26C5oyjL1gkXsBeYwHHjvGvCcidr9 > adr.txt Step2: $ printf $( cat adr.txt | sed 's/[[:xdigit:]]\{2\}/\\x&/g' ) >adr.hex Step3: $ openssl dgst -sha256 -binary <adr.hex >tmp_sha256.hex Step4: $ openssl dgst -ripemd160 <tmp_sha256.hex ## result should be: 56379c7bcd6b41188854e74169f844e8676cf8b8
Now I want to do this in Java. I currently have the following code. No matter what I try, I dont get the correct result. :(
String address = "1L88S26C5oyjL1gkXsBeYwHHjvGvCcidr9"; // step 1 System.out.println("address: " + address); byte[] addressHex = address.getBytes(StandardCharsets.UTF_8); // step 2 MessageDigest digest = MessageDigest.getInstance("SHA-256"); byte[] hash = digest.digest(addressHex); // step 3 RIPEMD160Digest digest2 = new RIPEMD160Digest(); // steps 4 digest2.update(hash, 0, hash.length); byte[] out = new byte[20]; digest2.doFinal(out, 0); System.out.println(bytesToHex(out)); // = db151e871af66b1323893e3f527e22f7684718af // should be 56379c7bcd6b41188854e74169f844e8676cf8b8
Can someone help me? I think the problem is somewhere doing the conversion String/hex/byte ...? I tried really hard, but cannot find the correct way to do it.
I also tried to convert the address to hex and after that to bytes, but doesnt work neither. :/
