NAME
EVP_CIPHER-NULL - The NULL EVP_CIPHER implementation
DESCRIPTION
Header "DESCRIPTION" Support for a NULL symmetric encryption using the EVP_CIPHER API.
This is used when the TLS cipher suite is TLS_NULL_WITH_NULL_NULL.
This does no encryption (just copies the data) and has a mac size of zero.
"Algorithm Name"
Subsection "Algorithm Name" The following algorithm is available in the default provider:
"""NULL""" 4
Item """NULL""" Parameters
Subsection "Parameters" This implementation supports the following parameters:
Gettable EVP_CIPHER parameters Subsection "Gettable EVP_CIPHER parameters"
See "Gettable EVP_CIPHER parameters" in EVP_EncryptInit\|(3)
Gettable EVP_CIPHER_CTX parameters Subsection "Gettable EVP_CIPHER_CTX parameters"
"""keylen"" (OSSL_CIPHER_PARAM_KEYLEN) <unsigned integer>" 4
Item """keylen"" (OSSL_CIPHER_PARAM_KEYLEN) <unsigned integer>" 0
"""ivlen"" (OSSL_CIPHER_PARAM_IVLEN and <OSSL_CIPHER_PARAM_AEAD_IVLEN) <unsigned integer>" 4
Item """ivlen"" (OSSL_CIPHER_PARAM_IVLEN and <OSSL_CIPHER_PARAM_AEAD_IVLEN) <unsigned integer>" """tls-mac"" (OSSL_CIPHER_PARAM_TLS_MAC) <octet ptr>" 4
Item """tls-mac"" (OSSL_CIPHER_PARAM_TLS_MAC) <octet ptr>"
See "PARAMETERS" in EVP_EncryptInit\|(3) for further information.
Settable EVP_CIPHER_CTX parameters Subsection "Settable EVP_CIPHER_CTX parameters"
"""tls-mac-size"" (OSSL_CIPHER_PARAM_TLS_MAC_SIZE) <unsigned integer>" 4
Item """tls-mac-size"" (OSSL_CIPHER_PARAM_TLS_MAC_SIZE) <unsigned integer>" See "PARAMETERS" in EVP_EncryptInit\|(3) for further information.
