similar to the steps taken in Signing the data, append the MD5 secret key to the character string to generate a new string. Then, calculate this new string with the MD5 signature algorithm. After the 32-byte signature result string is generated, verify whether the value is equal to the val...
2、Hash the JSON content by using the SHA256withRSA algorithm. Then use the client's RSA private key to sign the value to obtain the signature. To achieve a better security level, the length of the RSA key/pairs must be 2048 bits. The following sample illustrates a raw signature: sXSGd...
public static String sign(byte[] privateKey, String content) { try { java.security.Signature signature = java.security.Signature .getInstance("SHA256withRSA"); PrivateKey priKey = KeyFactory.getInstance("RSA").generatePrivate(new PKCS8EncodedKeySpec(privateKey)); signature.initSign(priKey); signa...
RSA and AES algorithms, on the digital signature had been done in this study to maintain data security. The RSA algorithm was used during the process of giving digital signature, while the AES algorithm was used during the process of encoding a message that will be sent to the receiver. ...
PURPOSE: A method and an apparatus for digital signature using a CRT(Chinese Remainder Theorem)-based RSA(Rivest, Shamir, and Adleman) public key encoding method are provided to reduce the amount of calculation by using a compatible structure with an existing system without adding new parameters....

Digital signatures are based on public key cryptography, also known asasymmetric cryptography. Using a public key algorithm, such as Rivest-Shamir-Adleman, orRSA, two keys are generated, creating a mathematically linked pair of keys: one private and one public. ...
To create a digital signature, you would take the message or file you would like to sign and run it through ahash function. After that, you take the resulting message digest or hash, combine it with your private key, and then run them through a signing algorithm likeRSA or DSA. The fi...
