SHA is not used in RSA. However, cryptographic protocols like SSL, SSH and others, use different algorithms like SHA and RSA for different purposes. SSL uses RSA (encryption) or DH (with RSA, DSA or ECDSA signature) for key negotiation and AES or 3DES for data encryption.

Is using "SHA-256 with RSA-2048 Encryption" a secure The technical answer is actually "no, because SHA-256 with RSA-2048 Encryption is not a certificate hashing algorithm.However, SHA-256 is a perfectly good secure hashing algorithm and quite suitable for use on certificates, and 2048-bit RSA is a good signing algorithm (signing is not the same as encrypting).Using 2048-bit RSA with SHA-256 is a secure signing scheme for a certificate. c# - How can I sign a file using RSA and SHA256 with .NET RSA + SHA256 can and will work Your later example may not work all the time, it should use the hash algorithm's OID, rather than it's name. As per your first example, this is obtained from a call to CryptoConfig.MapNameToOID(AlgorithmName) where AlgorithmName is what you are providing (i.e. "SHA256").. First you are going to need is the certificate with the private key. Cipher suite definitions - IBM

HOWTO: Disable weak protocols, cipher suites and hashing

May 28, 2020 · "OpenSSH's advisory was worded very confusingly, but the way it works is that ssh-rsa *keys* can be used with both the ssh-rsa *algorithm* and the rsa-sha2-256 *algorithm*. If both sides support the latter then there is no SHA-1 in use," said security consultant Hector Martin on Twitter . Signature algorithm ALG_RSA_SHA_PKCS1_PSS generates a 20-byte SHA-1 digest, pads it according to the PKCS#1-PSS scheme (IEEE 1363-2000), and encrypts it using RSA. To request this algorithm using the getInstance(byte, byte, byte, boolean) method use the MessageDigest.ALG_SHA, SIG_CIPHER_RSA, Cipher.PAD_PKCS1_PSS constants respectively.
