hi! i got some problems with including signature checking to a program... on one side it runs on php and uses OpenSSL to sign a message... on the other side there is the JAVA code... i can´t get the java code to verify the OpenSSL signature and vice versa. i think OpenSSL uses the PKCS7 standard (not sure what this does mean yet)... iam using bouncycastle on java... if i decrypt the signed message i get 35 bytes instead of 20... (SHA1 hash) well iam using ("RSA/NONE/PKCS1PADDING") but if PKCS7 padding is used or something is just different that would cause the problem... iam thankfull for every help John
