Malleability is often an undesirable property in a general-purpose cryptosystem, since it allows an attacker to modify the contents of a message. For example, suppose that a bank uses a stream cipher to hide its financial information, and a user sends an encrypted message containing, say, "TRANSFER $0000100.00 TO ACCOUNT #199."
Malleability, a similar mechanical property, is characterized by a material's ability to deform plastically without failure under compressive stress. [8] [9] Historically, materials were considered malleable if they were amenable to forming by hammering or rolling. [10] Lead is an example of a material which is relatively malleable but not ductile.

The alloy's natural malleability is an obvious physical advantage, but it is also naturally aseptic. [20] Some brasswind instrument manufacturers use 92.5% sterling silver as the material for making their instruments, including the flute and saxophone.
A material property is an intensive property of a material, i.e., a physical property or chemical property that does not depend on the amount of the material. These quantitative properties may be used as a metric by which the benefits of one material versus another can be compared, thereby aiding in materials selection.
The malleability of the solid metals led to the first attempts to craft metal ornaments, tools, and weapons. Meteoric iron containing nickel was discovered from time to time and, in some respects this was superior to any industrial steel manufactured up to the 1880s when alloy steels become prominent.
For every family with | |, there exist non-malleable codes against with rate arbitrarily close to 1 − (this is achieved w.h.p. by a randomized construction). [5]For families of size (()) against which there is no non-malleable code of rate 1 − (in fact this is the case w.h.p for a random family of this size).
Disposal of munitions with plastic explosives; note the malleability of the white plastic explosive charges Plastic explosive is a soft and hand-moldable solid form of explosive material . Within the field of explosives engineering , plastic explosives are also known as putty explosives [ 1 ] or blastics .
