What is the difference between SHA256WITHRSA and SHA256WITHRSAENCRYPTION digest algorithms? I installed djigzo on my android phone and I want to use it for smime mail.
I don't know the difference between choosing SHA256WITHRSA and SHA256WITHRSAENCRYPTION digest algorithms in the settings.

My online search only returned OIDs and code samples. Can you enlighten me?
It seems that djigzo uses bouncycastle and if you look in the source at the DefaultSignatureAlgorithmIdentifierFinder, e.g., here, then you find:

algorithms.put("SHA256WITHRSAENCRYPTION", PKCSObjectIdentifiers.sha256WithRSAEncryption);
algorithms.put("SHA256WITHRSA", PKCSObjectIdentifiers.sha256WithRSAEncryption);


Thus, it seems that both refer to sha256WithRSAEncryption, which means RSA with SHA-256 and PKCS #1 v1.5 padding.
