Is it possible to use "RSAwithSHA1" as used for Signature.getInstance("RSAwithSHA1") in PHP?
I've generated the keys using:
openssl genrsa -out key.pem 1024

SHA1withRSA (**not** RSAwithSHA1, first the hash is calculated, then the RSA modular exponentiation is used) indicates the PKCS#1 v1.5 padding scheme for signature generation using a SHA-1 message digest / secure hash. PHP also implements this scheme. You can see how in the duplicate. – Maarten Bodewes Nov 21 '15 at 10:41
