Class RSAOtherPrimeInfo

java.lang.Object
- java.security.spec.RSAOtherPrimeInfo

```
public class RSAOtherPrimeInfo
extends Object
```
This class represents the triplet (prime, exponent, and coefficient) inside RSA's OtherPrimeInfo structure, as defined in the PKCS#1 v2.1. The ASN.1 syntax of RSA's OtherPrimeInfo is as follows:
```
 OtherPrimeInfo ::= SEQUENCE {
   prime INTEGER,
   exponent INTEGER,
   coefficient INTEGER
   }

 
```
Since:
