Description
This function selects the message digest algorithm to use, and allocates internal structures. It should be called after mbedtls_md_init() or mbedtls_md_free(). Makes it necessary to call mbedtls_md_free() later.
This function extracts the message-digest size from the message-digest information structure.
This function calculates the message-digest of a buffer, with respect to a configurable message-digest algorithm in a single call. The result is calculated as Output = message_digest(input buffer).
This function selects the message digest algorithm to use, and allocates internal structures. It should be called after mbedtls_md_init() or mbedtls_md_free(). Makes it necessary to call mbedtls_md_free() later. \deprecated Superseded by mbedtls_md_setup() in 2.0.0
