通过这个方法,我们可以得到每个字符对应的字节值。 步骤二:将字节数组转换成HEX格式的字符串 StringBuilderhexString=newStringBuilder();for(byteb:bytes){hexString.append(String.format("%02X",b));// 将字节值转换成HEX格式的字符串}Stringhex=hexString.toString();// 将StringBuilder转换成String 1. 2. 3. 4...

I have String hash in hex form ("e6fb06210fafc02fd7479ddbed2d042cc3a5155e") and I would like to compare it to crypt.digest(). One way, which works fine, is to convert crypt.digest() to hex, but I would like to avoid multiple conversions and rather convert hash from hex form (...
