Expand description

RSA PKCS#1 1.5 signatures using SHA-256 for keys of 2048-8192 bits, with illegally absent AlgorithmIdentifier parameters.

RFC4055 says on sha256WithRSAEncryption and company:

When any of these four object identifiers appears within an AlgorithmIdentifier, the parameters MUST be NULL. Implementations MUST accept the parameters being absent as well as present.

This algorithm covers the absent case, RSA_PKCS1_2048_8192_SHA256 covers the present case.
