# 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.
