|  | # WORKED-OUT EXAMPLE FOR RSAES-OAEP | ||
|  | # ================================= | ||
|  | #  | ||
|  | # This file gives an example of the process of | ||
|  | # encrypting and decrypting a message with | ||
|  | # RSAES-OAEP as specified in PKCS #1 v2.1. | ||
|  | # | ||
|  | # The message is a bit string of length 128, | ||
|  | # while the size of the modulus in the public | ||
|  | # key is 1024 bits. The second representation | ||
|  | # of the private key is used, which means that | ||
|  | # CRT is applied in the decryption process. | ||
|  | #  | ||
|  | # The underlying hash function is SHA-1; the | ||
|  | # mask generation function is MGF1 with SHA-1 | ||
|  | # as specified in PKCS #1 v2.1. | ||
|  | # | ||
|  | # This file also contains a demonstration of | ||
|  | # the RSADP decryption primitive with CRT. | ||
|  | # Finally, DER encodings of the RSA keys are | ||
|  | # given at the end of the file. | ||
|  | # | ||
|  | #  | ||
|  | # Integers are represented by strings of octets | ||
|  | # with the leftmost octet being the most | ||
|  | # significant octet. For example,  | ||
|  | # | ||
|  | #           9,202,000 = (0x)8c 69 50.  | ||
