How to verify a signature in OpenSSL?
Obviously this step is performed on the receivers end. The -verify argument tells OpenSSL to verify signature using the provided public key. The signature file is provided using -signature argument. When the signature is valid, OpenSSL prints “Verified OK”. It is also possible to calculate the digest and signature separately.

What is genrsa -out key in OpenSSL?
openssl genrsa -out key.pem 4096 The private key is in key.pem file and public key in key.pub file. The sender uses the private key to digitally sign documents, and the public key is distributed to recipients. To sign a data file (data.zip in the example), OpenSSL digest (dgst) command is used.

How to verify a signature using RSA?
The context is initialized with the hash function used (SHA-256 in our case) and the public key. The original message is then provided and finally the verification is performed. Putting this all together, you can verify a signature given the original text, the signature and public key as follows: RSA* publicRSA = createPublicRSA(publicKey);
