The return type of all CryptoJS.<blockcipher>.decrypt() functions is a WordArray which is the native representation of binary data in CryptoJS. When you force it to be printed (automatically calling toString()), the binary data that it contains will be Hex encoded.

If you want to have a different encoding, then you need to specify it. Here are some examples:

console.log(decrypted.toString()); // Hex encoded
console.log(decrypted.toString(CryptoJS.enc.Hex)); // Hex encoded
console.log(CryptoJS.enc.Hex.stringify(decrypted)); // Hex encoded

console.log(decrypted.toString(CryptoJS.enc.Utf8)); // UTF-8 encoded
console.log(CryptoJS.enc.Utf8.stringify(decrypted)); // UTF-8 encoded

console.log(decrypted.toString(CryptoJS.enc.Base64)); // Base64 encoded
console.log(CryptoJS.enc.Base64.stringify(decrypted)); // Base64 encoded
