# 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.
