Public predicates
.. index:: encrypt/4 .. _ecb/0::encrypt/4:
encrypt/4 ^^^^^^^^^^^^^
Encrypts block-aligned plaintext without padding.
| Compilation flags:
| static
| Template:
| encrypt(Cipher,Key,Plaintext,Ciphertext)
| Mode and number of proofs:
| encrypt(+object_identifier,+list(byte),+list(byte),--list(byte)) - one_or_error
| Exceptions:
| Cipher is a variable:
| instantiation_error
| Cipher is neither a variable nor a prepared-key block cipher object:
| domain_error(block_cipher,Cipher)
| Plaintext is a variable or a partial list:
| instantiation_error
| Plaintext is neither a partial list nor a list:
| type_error(list,Plaintext)
| An element Byte of the Plaintext list is neither a variable nor an integer:
| type_error(integer,Byte)
| An element Byte of the Plaintext list is an integer but not a valid byte:
| domain_error(byte,Byte)
| Plaintext length is not block aligned:
| domain_error(block_aligned_byte_length(BlockSize),Plaintext)
.. index:: decrypt/4 .. _ecb/0::decrypt/4:
decrypt/4 ^^^^^^^^^^^^^
Decrypts block-aligned ciphertext without removing padding.
| Compilation flags:
| static
| Template:
| decrypt(Cipher,Key,Ciphertext,Plaintext)
| Mode and number of proofs:
| decrypt(+object_identifier,+list(byte),+list(byte),--list(byte)) - one_or_error
| Exceptions:
| Cipher is a variable:
| instantiation_error
| Cipher is neither a variable nor a prepared-key block cipher object:
| domain_error(block_cipher,Cipher)
| Ciphertext is a variable or a partial list:
| instantiation_error
| Ciphertext is neither a partial list nor a list:
| type_error(list,Ciphertext)
| An element Byte of the Ciphertext list is neither a variable nor an integer:
| type_error(integer,Byte)
| An element Byte of the Ciphertext list is an integer but not a valid byte:
| domain_error(byte,Byte)
| Ciphertext length is not block aligned:
| domain_error(block_aligned_byte_length(BlockSize),Ciphertext)
.. index:: encrypt_padded/4 .. _ecb/0::encrypt_padded/4:
encrypt_padded/4 ^^^^^^^^^^^^^^^^^^^^
Pads plaintext using PKCS#7 and encrypts it.
| Compilation flags:
| static
| Template:
| encrypt_padded(Cipher,Key,Plaintext,Ciphertext)
| Mode and number of proofs:
| encrypt_padded(+object_identifier,+list(byte),+list(byte),--list(byte)) - one_or_error
| Exceptions:
| Cipher is a variable:
| instantiation_error
| Cipher is neither a variable nor a prepared-key block cipher object:
| domain_error(block_cipher,Cipher)
| Plaintext is a variable or a partial list:
| instantiation_error
| Plaintext is neither a partial list nor a list:
| type_error(list,Plaintext)
| An element Byte of the Plaintext list is neither a variable nor an integer:
| type_error(integer,Byte)
| An element Byte of the Plaintext list is an integer but not a valid byte:
| domain_error(byte,Byte)
| Cipher block size exceeds the PKCS#7 limit:
| domain_error(pkcs7_block_size,BlockSize)
.. index:: decrypt_padded/4 .. _ecb/0::decrypt_padded/4:
decrypt_padded/4 ^^^^^^^^^^^^^^^^^^^^
Decrypts ciphertext and validates and removes PKCS#7 padding.
| Compilation flags:
| static
| Template:
| decrypt_padded(Cipher,Key,Ciphertext,Plaintext)
| Mode and number of proofs:
| decrypt_padded(+object_identifier,+list(byte),+list(byte),--list(byte)) - one_or_error
