Load the RSA public key from the PEM format. The following steps demonstrate how to use the RSA public key to decrypt the data: MF8CSwC0BKDfEdHKz/GhoEjU1XP5U6YsWD10klknVhpteh4rFAQlJq9wtVBUc5DqbsdI0w/bga20kODDahmGtASy9fae9dobZj5ZUJEw5wIQMJz+2XGf4qXiDJu0R2U4Kw= The prime numbers p and q should be at least 1024-bit RSA is an asymmetric cryptographic algorithm which is used for encryption purposes so that only the required sources should know the text and no third party should be allowed to decrypt the text as it is encrypted.

Java encrypt/decrypt with RSA generating keys from modulus and exponents. encryption with java RSA and decryption with BigInteger.
